[LTP] [PATCH] syscalls: ulimit01; Convert to the new library

Cyril Hrubis chrubis@suse.cz
Wed Mar 4 15:44:24 CET 2026


Linux does not implement UL_GMEMLIM, UL_GDESLIM and UL_GSHMEMLIM so we
keep only the UL_GETFSIZE and UL_SETFSIZE.

- *
- *    TEST CASES
- *
- * 	1.) ulimit(2) returns...(See Description)
- *
- *    INPUT SPECIFICATIONS
- * 	The standard options for system call tests are accepted.
- *	(See the parse_opts(3) man page).
- *
- *    OUTPUT SPECIFICATIONS
- *$
- *    DURATION
- * 	Terminates - with frequency and infinite modes.
- *
- *    SIGNALS
- * 	Uses SIGUSR1 to pause before test if option set.
- * 	(See the parse_opts(3) man page).
- *
- *    RESOURCES
- * 	None
- *
- *    ENVIRONMENTAL NEEDS
- * 	The libcuts.a and libsys.a libraries must be included in
- *	the compilation of this test.
- *
- *    SPECIAL PROCEDURAL REQUIREMENTS
- * 	None
- *
- *    INTERCASE DEPENDENCIES
- * 	None
- *
- *    DETAILED DESCRIPTION
- *	This is a Phase I test for the ulimit(2) system call.  It is intended
- *	to provide a limited exposure of the system call, for now.  It
- *	should/will be extended when full functional tests are written for
- *	ulimit(2).
- *
- * 	Setup:
- * 	  Setup signal handling.
- *	  Pause for SIGUSR1 if option specified.
- *
- * 	Test:
- *	 Loop if the proper options are given.
- * 	  Execute system call
- *	  Check return code, if system call failed (return=-1)
- *		Log the errno and Issue a FAIL message.
- *	  Otherwise, Issue a PASS message.
- *
- * 	Cleanup:
- * 	  Print errno log and/or timing stats if options given
- *
