NAME
IrERRORS - error definitions
SYNOPSIS
#include <irapi.h>
DESCRIPTION
When IRAPI functions return a failure indication (typically
with a return value of IRR_FAIL), they also set the global
variable irError to indicate the cause of the error. The
irError variable is set to one of the values in the list
below.
In addition to failures detected when an activity is first
started, the IRAPI library may detect errors that occur
while attempting to complete a requested activity that was
successfully initiated by a function that returned IRR_OK
(or some other success value). In these cases, a DONE event
(IRE_ANSWER_DONE, IRE_PLAY_DONE, etc.) is generated with an
event_mod1 value of IREM_ERROR and the event_mod2 is set to
one of the values in the list below.
If the following explanation of errors is not sufficient for
resolving the problem, it may be useful to try reproducing
the problem with tracing enabled. See irTrace(1IRAPI) in
Intuity CONVERSANT VIS V5.0 Command Reference, 585-310-230,
for further information about the trace command.
The following errors are possible:
IRER_APIERROR Indicates a library call to a third party
API resulted in an error that has an asso-
ciated API specific error value. Applica-
tions receiving this error as the result
of a function failure should check
irSysError for the API specific error
value that was reported by the third party
API call. Applications receiving this
error as the result of a DONE event with
event_mod1 set to IREM_ERROR and
event_mod2 set to IRER_APIERROR, should
check event_mod3 for the API specific
error that was reported by the API call.
IRER_BADRANGE Indicates an invalid range of numbers was
provided (starting value was greater than
ending value)
IRER_BADSTATE Indicates a function was called for a
channel with an inappropriate library
state
IRER_CONNECTFAIL Indicates that an attempt to print or
record a FAX failed due to a failure to
connect with the far end FAX device.
IRER_DIERROR Indicates that the FAX Device Interface
process reported an error.
IRER_DRIVER_ERROR Indicates a network interface driver call
or SP driver call resulted in an error.
The error may have been detected by the
network, pack file, driver, input process,
or library helper functions for the
driver. Applications receiving this error
as the result of a function failure should
check irSysError for the error number that
was reported by the driver call. Applica-
tions receiving this error as the result
of a DONE event with event_mod1 set to
IREM_ERROR and event_mod2 set to
IRER_DRIVER_ERROR, should check event_mod3
for the error number that was reported by
the driver call. Unlike IRER_SYSERROR
described below, the error numbers are
specific to the type of driver that is
being used. The irSysError value should
not be interpreted as being a UNIX errno
value. Tracing or associated log messages
may be helpful to establish the context in
which the error is being reported.
IRER_ENDOFTABLE Indicates a function call resulted in a
query beyond the end of a table
IRER_FTT Indicates FAX failure to train with the
far end FAX device.
IRER_IDLE Indicates that FAX transmission terminated
due to unexpected line idling.
IRER_INCOMINGFAILED
Indicates that FAX record failed.
IRER_INTERNAL Indicates a function call resulted in an
internal library error
IRER_INVALID Indicates that a IRAPI function was passed
invalid or bad arguments
IRER_LINEDISABLE Indicates that the FAX line was disabled
during FAX transmission.
IRER_LINEHALT Indicates that the FAX line was halted
during FAX transmission.
IRER_LINEMALFUNCTION
Indicates that FAX transmission terminated
due to a line malfunction.
IRER_LOADERROR Indicates the irRegister function could
not load the required extension library
routines or encountered an error in trying
to execute them. The most common cause
for this error is when -lirEXT appears
after -lirAPI in a compile statement. The
-lirEXT must appear before the -lirAPI.
Extension library routines are contained
in either /usr/lib/libirEXT.so or in a
shared object library listed in
/vs/data/irSPI.libs.
IRER_MAXCHAN_TIMESLOTS
Indicates a function failed since it would
have required talking on more than the
maximum number of timeslots for that chan-
nel
IRER_MAXLEN Indicates that FAX record terminated due
to receipt of the maximum number of bytes
specified via irFAXRecord(3IRAPI).
IRER_NO_TIMESLOT Indicates that a play, say, code, or other
request failed since there was no allo-
cated "talk" and/or "listen" timeslot for
the channel. The "talk" timeslot may have
been released while a bridge was active,
or the timeslot may have been released
prematurely.
IRER_NODATA Indicates that a play or say request con-
tained no data
IRER_NOPROTOCOL Indicates that FAX transmission failed due
to no line protocol.
IRER_NORESOURCES Indicates that the Resources for the
requested service are non-existent or out
of service
IRER_NOREGISTER Indicates an IRAPI function call was made
prior to IRAPI process registration via
irRegister(3IRAPI)
IRER_NOTCOLLOCATED
Indicates functions could not be allocated
on a common resource.
IRER_NOTFOUND Indicates an object required to complete a
function call could not be found
IRER_OPERATORINT Indicates that FAX transmission failed due
to operator intervention.
IRER_OVERFLOW Indicates a function call resulted in some
overflow condition for an IRAPI data ele-
ment
IRER_OVERLAP Indicates an invalid overlap has been
detected in two ranges of numbers that
should have included one range of numbers
as a proper subset of the other
IRER_PERMISSION Indicates a function was called by a pro-
cess that has no permission to execute the
function
IRER_PREVIOUS_INIT
Indicates the forcible initialization of a
channel has failed because this process
already has a cid for this channel. This
error type is only expected to apply to
MTC and related programs since irInit nor-
mally creates a pending request for a
channel that is already owned by the same
process.
IRER_PROTOCOLERR Indicates that FAX transmission failed due
to a line protocol error.
IRER_PROTOCOLTIMEOUT
Indicates that FAX transmission failed due
to a line protocol timeout.
IRER_REDUNDANT Indicates a function was called for which
the service was already enabled. For
example, calling irStartEcho(3IRAPI) when
echo cancellation has already been
started. When this error is returned, the
service remains active.
IRER_REMOTEDCN Indicates that FAX transmission failed due
to a remote disconnect.
IRER_RESOURCEBUSY Indicates a function was called but
resources were not immediately available
to serve the needs of the function. When
provided as a modifier to an IRE_CALL_DONE
event with an IREM_ERROR modifier, this
indicates that a pending request for in-
use CCA resources has timed-out.
IRER_RESOURCE_REMOVED
Indicates a service or activity was inter-
rupted by a maintenance process that for-
cibly removed the resources required to
perform the service or activity. This
error code is provided as a modifier to a
IRE_<activity>_DONE event following the
IREM_ERROR modifier.
IRER_RESTRICTED Indicates resources required for the
called function have been explicitly res-
tricted from the cid via
irRestrictResource(3IRAPI)
IRER_RTN Indicates that FAX transmission terminated
due to a failure to retransmit a page of
unacceptable quality.
IRER_SERVICESTATE Indicates a function was called for a
channel with an inappropriate service
state
IRER_SHM_CORRUPTED
Indicates the DEVTBL shared memory is cor-
rupted. Stop and start the voice system.
IRER_SHUTDOWN Indicates that FAX transmission failed due
server process shutdown.
IRER_SYSERROR Indicates a UNIX system call, driver call,
or library call resulted in an error that
has an associated UNIX errno. Applica-
tions receiving this error as the result
of a function failure should check
irSysError for the errno that was reported
by the UNIX system call. Applications
receiving this error as the result of a
DONE event with event_mod1 set to
IREM_ERROR and event_mod2 set to
IRER_SYSERROR, should check event_mod3 for
the errno that was reported by the UNIX
system call. IRER_SYSERROR differs from
IRER_DRIVER_ERROR in that irSysError
should be a valid UNIX errno when
IRER_SYSERROR is reported. Further general
information about UNIX errno values can be
found intro(2).
IRER_TIMESLOTS_BUSY
Indicates a function failed since all
dynamically allocated timeslots were in
use and the necessary timeslot could not
be allocated. The problem will go away
when timeslots are freed, but may indicate
that the system is configured for too many
channels for the activity requested.
IRER_TSBUS Indicates a function failed since one or
more channels were not on a TDM bus, or
the time-slots could not be connected for
the type of communication requested
IRER_UNSUPPORTED Indicates a function call requested an
operation that could not be supported on
the channel telephony
IRER_OBSOLETE Indicates an obsolete function call or
parameter.
