NAME

       explain_setvbuf_or_die - stream buffering operations and report errors

SYNOPSIS

       #include <libexplain/setvbuf.h>
       void explain_setvbuf_or_die(FILE *fp, char *data, int mode, size_t size);
       int explain_setvbuf_on_error(FILE *fp, char *data, int mode, size_t size);

DESCRIPTION

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

       The  explain_setvbuf_on_error  function  is  used  to  call the setvbuf(3) system call. On
       failure an explanation will be printed to stderr,  obtained  from  the  explain_setvbuf(3)
       function, but still returns to the caller.

       fp      The fp, exactly as to be passed to the setvbuf(3) system call.

       data    The data, exactly as to be passed to the setvbuf(3) system call.

       mode    The mode, exactly as to be passed to the setvbuf(3) system call.

       size    The size, exactly as to be passed to the setvbuf(3) system call.

RETURN VALUE

       The  explain_setvbuf_or_die  function  only  returns  on  success, see setvbuf(3) for more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_setvbuf_on_error function always returns  the  value  return  by  the  wrapped
       setvbuf(3) system call.

EXAMPLE

       The  explain_setvbuf_or_die  function  is  intended to be used in a fashion similar to the
       following example:
              explain_setvbuf_or_die(fp, data, mode, size);
