explain_vfork_or_die(3) Library Functions Manual explain_vfork_or_die(3) NAME explain_vfork_or_die - create a child process and report errors SYNOPSIS #include <libexplain/vfork.h> pid_t explain_vfork_or_die(void); pid_t explain_vfork_on_error(void); DESCRIPTION The explain_vfork_or_die function is used to call the vfork(2) system call. On failure an explanation will be printed to stderr, obtained from the ex- plain_vfork(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_vfork_on_error function is used to call the vfork(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_vfork(3) function, but still returns to the caller. RETURN VALUE The explain_vfork_or_die function only returns on success, see vfork(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_vfork_on_error function always returns the value return by the wrapped vfork(2) system call. EXAMPLE The explain_vfork_or_die function is intended to be used in a fashion simi- lar to the following example: pid_t result = explain_vfork_or_die(); SEE ALSO vfork(2) create a child process and block parent explain_vfork(3) explain vfork(2) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_vfork_or_die(3)
