explain_close_or_die - close a file descriptor and report errors
#include <libexplain/close.h>
void explain_close_or_die(int fildes);
The
explain_close_or_die function is used to call the
close(2)
system call. On failure an explanation will be printed to
stderr,
obtained from
explain_close(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_close_or_die(fildes);
- fildes
- The fildes, exactly as to be passed to the close(2) system
call.
- Returns:
- This function only returns on success. On failure, prints an explanation
and exits.
- close(2)
- close a file descriptor
- explain_close(3)
- explain close(2) errors
- exit(2)
- terminate the calling process
