From signal manpage on Linux: |
| |
" According to POSIX (3.3.1.3) it is unspecified what happens when |
| |
SIGCHLD is set to SIG_IGN. Here the BSD and SYSV behaviours differ, |
| |
causing BSD software that sets the action for SIGCHLD to SIG_IGN to |
| |
fail on Linux." |
| |
|
| |
On Linux, when you perform a "system" it calls wait(). If you have ignored |
| |
SIGCHLD, a POSIX-conformant system is allowed to collect zombies immediately |
| |
rather than holding them for you to wait for. And you end up with "system" |
| |
returning non-zero return code instead of zero return code for sucessfull |
| |
calls. |
| |
|
| |
HP-UX being a SYSV system behaves differently. |
