NAME

       explain_fread_or_die - binary stream input and report errors

SYNOPSIS

       #include <libexplain/fread.h>
       void explain_fread_or_die(void *ptr, size_t size, size_t nmemb, FILE *fp);

DESCRIPTION

       The explain_fread_or_die function is used to call the fread(3) system call.  On failure an
       explanation will be printed to  stderr,  obtained  from  explain_fread(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:
              size_t how_many = explain_fread_or_die(ptr, size, nmemb, fp);

       ptr     The ptr, exactly as to be passed to the fread(3) system call.

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

       nmemb   The nmemb, exactly as to be passed to the fread(3) system call.

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

       Returns:
               This  function  only returns on success, the number read or 0 on end‐of‐input.  On
               failure, prints an explanation and exits.
