explain_futimesat_or_die − change timestamps of a file relative to a directory and report errors
#include <libexplain/futimesat.h>
void explain_futimesat_or_die(int fildes, const char *pathname, const struct timeval *data);
int explain_futimesat_on_error(int fildes, const char *pathname, const struct timeval *data);
The explain_futimesat_or_die function is used to call the futimesat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_futimesat(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_futimesat_on_error function is used to call the futimesat(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_futimesat(3) function, but still returns to the caller.
fildes |
The fildes, exactly as to be passed to the futimesat(2) system call. |
pathname
The pathname, exactly as to be passed to the futimesat(2) system call.
data |
The data, exactly as to be passed to the futimesat(2) system call. |
The explain_futimesat_or_die function only returns on success, see futimesat(2) for more information. On failure, prints an explanation and exits, it does not return.
The explain_futimesat_on_error function always returns the value return by the wrapped futimesat(2) system call.
The explain_futimesat_or_die function is intended to be used in a fashion similar to the following example:
explain_futimesat_or_die(fildes, pathname, data);
change timestamps of a file relative to a directory
explain futimesat(2) errors
terminate the calling process |
