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 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  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
       similar 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
