NAME explain_setsid_or_die - sets process group ID and report errors
SYNOPSIS #include <libexplain/setsid.h> pid_t explain_setsid_or_die(void); pid_t explain_setsid_on_error(void);
DESCRIPTION The explain_setsid_or_die function is used to call the setsid(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_setsid(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_setsid_on_error function is used to call the setsid(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_setsid(3) function, but still returns to the caller.
RETURN VALUE The explain_setsid_or_die function only returns on success, see setsid(2) for more infor‐ mation. On failure, prints an explanation and exits, it does not return. The explain_setsid_on_error function always returns the value return by the wrapped set‐ sid(2) system call.
EXAMPLE The explain_setsid_or_die function is intended to be used in a fashion similar to the fol‐ lowing example: explain_setsid_or_die();
SEE ALSO setsid(2) creates a session and sets the process group ID explain_setsid(3) explain setsid(2) errors exit(2) terminate the calling process
