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 following 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 explanation and exits.
