*
* FUNCTION NAME : usctest.h
*
* FUNCTION TITLE : System Call Test Macros
*
* SYNOPSIS:
* See DESCRIPTION below.
*
* AUTHOR : William Roske
*
* INITIAL RELEASE : UNICOS 7.0
*
* DESCRIPTION
* TEST(SCALL) - calls a system call
* TEST_VOID(SCALL) - same as TEST() but for syscalls with no return value.
* TEST_CLEANUP - print the log of errno return counts if STD_ERRNO_LOG
* is set.
* TEST_PAUSEF(HAND) - Pause for SIGUSR1 if the pause flag is set.
* Use "hand" as the interrupt handling function
* TEST_PAUSE - Pause for SIGUSR1 if the pause flag is set.
* Use internal function to do nothing on signal and go on.
* TEST_LOOPING(COUNTER) - Conditional to check if test should
* loop. Evaluates to TRUE (1) or FALSE (0).
* TEST_ERROR_LOG(eno) - log that this errno was received,
* if STD_ERRNO_LOG is set.
* TEST_EXP_ENOS(array) - set the bits in TEST_VALID_ENO array at
* positions specified in integer "array"
*
* RETURN VALUE
* TEST(SCALL) - Global Variables set:
* int TEST_RETURN=return code from SCALL
* int TEST_ERRNO=value of errno at return from SCALL
* TEST_VOID(SCALL) - Global Variables set:
* int TEST_ERRNO=value of errno at return from SCALL
* TEST_CLEANUP - None.
* TEST_PAUSEF(HAND) - None.
* TEST_PAUSE - None.
* TEST_LOOPING(COUNTER) - True if COUNTER < STD_LOOP_COUNT or
* STD_INFINITE is set.
* TEST_ERROR_LOG(eno) - None
* TEST_EXP_ENOS(array) - None
*
* KNOWN BUGS
* If you use the TEST_PAUSE or TEST_LOOPING macros, you must
* link in parse_opts.o, which contains the code for those functions.
