|

|
|

|

|
|
* 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.
