acl_error — convert an ACL error code to a text message
Library
Linux Access Control Lists library (libacl, -lacl).
Synopsis
#include <sys/types.h>
#include <acl/libacl.h>
const char *
acl_error(int code);
Description
The acl_error() function converts an ACL error code such as returned by the acl_check() function to a text message describing the error condition. In the “POSIX” locale, acl_check() returns the following descriptions for the error codes.
- ACL_MULTI_ERROR
“Multiple entries”
- ACL_DUPLICATE_ERROR
“Duplicate entries”
- ACL_MISS_ERROR
“Missing or wrong entry”
- ACL_ENTRY_ERROR
“Invalid entry type”
Return Value
The acl_error() function returns a text message if the error code is recognized, and a value of (const char *)NULL otherwise.
Standards
This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned).
