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

     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).
