NAME

       explain_mknod_or_die - create a special or ordinary file and report errors

SYNOPSIS

       #include <libexplain/mknod.h>
       void explain_mknod_or_die(const char *pathname, mode_t mode, dev_t dev);
       int explain_mknod_on_error(const char *pathname, mode_t mode, dev_t dev);

DESCRIPTION

       The  explain_mknod_or_die function is used to call the mknod(2) system call. On failure an
       explanation will be printed to stderr, obtained from the  explain_mknod(3)  function,  and
       then the process terminates by calling exit(EXIT_FAILURE).

       The  explain_mknod_on_error  function is used to call the mknod(2) system call. On failure
       an explanation will be printed to stderr, obtained from the explain_mknod(3) function, but
       still returns to the caller.

       pathname
               The pathname, exactly as to be passed to the mknod(2) system call.

       mode    The mode, exactly as to be passed to the mknod(2) system call.

       dev     The dev, exactly as to be passed to the mknod(2) system call.

RETURN VALUE

       The  explain_mknod_or_die  function  only  returns  on  success,  see  mknod(2)  for  more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_mknod_on_error function  always  returns  the  value  return  by  the  wrapped
       mknod(2) system call.

EXAMPLE

       The  explain_mknod_or_die  function  is  intended  to  be used in a fashion similar to the
       following example:
              explain_mknod_or_die(pathname, mode, dev);
