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 explain_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 informa‐ tion. 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 similar to the fol‐ lowing example: pid_t result = explain_vfork_or_die();
