- >From POSIX.2 Draft 11 (unchanged for several drafts):
-
- B.3.1.3 Returns
-
- If command is NULL, the system() function shall return nonzero.
-
- If comamnd is not NULL, the system() function shall return the
- termination status of the command language interpreter in the format
- specified by the waitpid() function in POSIX.1. The termination status
- of the c.l.i. is as specified by the sh utility, except that if some
- error prevents the c.l.i. from executing after the child process is
- created, the return value from system() shall be as of the c.l.i.
- had terminated using exit(127) or _exit(127). If a child process
- cannot be created, or if the terminaton status of the c.l.i. cannot
- be obtained, system() shall return -1 and set errno to indicate the
- error.
