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.
