NAME

       explain_lseek_or_die - reposition file offset and report errors

SYNOPSIS

       #include <libexplain/lseek.h>
       long long explain_lseek_or_die(int fildes, long long offset, int whence);

DESCRIPTION

       The explain_lseek_or_die function is used to call the lseek(2) system call.  On failure an
       explanation will be printed to  stderr,  obtained  from  explain_lseek(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:
              long long result = explain_lseek_or_die(fildes, offset, whence);

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

       offset  The offset, exactly as to be passed to the lseek(2) system call.

       whence  The whence, exactly as to be passed to the lseek(2) system call.

       Returns:
               On successful, returns the resulting offset location as measured in bytes from the
               beginning of the file.  On failure, prints an explanation and exits.
