NAME
explain_statfs_or_die - get file system statistics and report errors
SYNOPSIS
#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);
DESCRIPTION
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.
EXAMPLE
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);
