explain_fgets_or_die(3)	   Library Functions Manual    explain_fgets_or_die(3)

NAME
       explain_fgets_or_die - input of strings and report errors

SYNOPSIS
       #include	<libexplain/fgets.h>
       char *explain_fgets_or_die(char *data, int data_size, FILE *fp);

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

       This function is	intended to be used in a fashion similar to  the  fol-
       lowing example:
	      explain_fgets_or_die(data, data_size, fp);

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

       data_size
	       The  data_size,	exactly	as to be passed	to the fgets(3)	system
	       call.

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

       Returns:
	       This function only returns on success;  data  when  a  line  is
	       read,  or  NULL on end-of-file.	On failure, prints an explana-
	       tion and	exits.
