Get file system statistics and report errors

Usage

#include <libexplain/statfs.h>

void explain_statfs_or_die(const char *pathname, struct statfs *data);
int explain_statfs_on_error(const char *pathname, struct statfs *data);

Overview

The explain_statfs_or_die function is used to call the statfs(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_statfs(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

The explain_statfs_on_error function is used to call the statfs(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_statfs(3) function, but still returns to the caller.

pathname

The pathname, exactly as to be passed to the statfs(2) system call.

data

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

Return value

The explain_statfs_or_die function only returns on success, see statfs(2) for more information. On failure, prints an explanation and exits, it does not return.

The explain_statfs_on_error function always returns the value return by the wrapped statfs(2) system call.

Examples

The explain_statfs_or_die function is intended to be used in a fashion similar to the following example:

explain_statfs_or_die(pathname, data);
