NAME

       explain_read_or_die - read from a file descriptor and report errors

SYNOPSIS

       #include <libexplain/read.h>
       long explain_read_or_die(int fildes, const void *data, long data_size);

DESCRIPTION

       The explain_read_or_die function is used to call the read(2) system call.  On failure an explanation will
       be  printed  to  stderr,  obtained  from  explain_read(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_read_or_die(fildes, data, data_size);

       fildes  The fildes, exactly as to be passed to the read(2) system call.

       data    The data, exactly as to be passed to the read(2) system call.

       data_size
               The data_size, exactly as to be passed to the read(2) system call.

       Returns:
               This function only returns on success.  On failure, prints an explanation and exits.
