GETEXCEPTIONPTRSQQ
Runtime Function: Returns a pointer to C runtime exception information pointers appropriate for use in signal handlers established with SIGNALQQ or direct calls to the C rtl signal( ) routine. This routine is only available for Windows.
Module
USE IFCORE
result = GETEXCEPTIONPTRSQQ( )
Results
The result type is INTEGER(4) on IA-32 architecture; INTEGER(8) on Intel® 64 architecture. The return value is the address of a data structure whose members are pointers to exception information captured by the C runtime at the time of an exception. This result value can then be used as the eptr argument to routine TRACEBACKQQ to generate a stack trace from a user-defined handler or to inspect the exception context record directly.
Calling GETEXCEPTIONPTRSQQ is only valid within a user-defined handler that was established with SIGNALQQ or a direct call to the C rtl signal( ) function.
For a full description of exceptions and error handling, see Error Handling.
Example
PROGRAM SIGTEST
USE IFCORE
...
R3 = 0.0E0
STS = SIGNALQQ(MY_HANDLER)
! Cause a divide by zero exception
R1 = 3.0E0/R3
...
END
INTEGER(4) FUNCTION MY_HANDLER(SIGNUM,EXCNUM)
USE IFCORE
...
EPTRS = GETEXCEPTIONPTRSQQ()
...
CALL TRACEBACKQQ("Application SIGFPE error!",USER_EXIT_CODE=-1,EPTR=EPTRS)
...
MY_HANDLER = 1
