DESCRIPTION         top

       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         top

       The acl_error() function returns a text message if the error code
       is recognized, and a value of (const char *)NULL otherwise.

STANDARDS         top

       This is a non-portable, Linux specific extension to the ACL
       manipulation functions defined in IEEE Std 1003.1e draft 17
       (“POSIX.1e”, abandoned).
