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 * stat(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 * * *#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#**/ #include #include #include #include #include #include #include #include "test.h" #include "usctest.h" void setup();
