explain_acl_set_file_or_die3
Set an acl by filename and report errors
Usage
#include <libexplain/acl_set_file.h>
void explain_acl_set_file_or_die(const char *pathname, acl_type_t type, acl_t acl);
int explain_acl_set_file_on_error(const char *pathname, acl_type_t type, acl_t acl);
Overview
The explain_acl_set_file_or_die function is used to call the acl_set_file(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_acl_set_file(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_acl_set_file_on_error function is used to call the acl_set_file(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_acl_set_file(3) function, but still returns to the caller.
pathname
|
The pathname, exactly as to be passed to the acl_set_file(3) system call. |
|---|---|

Return value
The explain_acl_set_file_or_die function only returns on success, see acl_set_file(3) for more information. On failure, prints an explanation and exits, it does not return.
The explain_acl_set_file_on_error function always returns the value return by the wrapped acl_set_file(3) system call.
Examples
The explain_acl_set_file_or_die function is intended to be used in a fashion similar to the following example:
explain_acl_set_file_or_die(pathname, type, acl);Releases
