71a889d1fbSRobert Watson.Va errno
72a889d1fbSRobert Watsonshall be set to indicate the error.
73a889d1fbSRobert Watson.Sh ERRORS
74a889d1fbSRobert WatsonIf any of the following conditions occur, these functions shall return
75a889d1fbSRobert Watson-1 and set
76a889d1fbSRobert Watson.Va errno
77a889d1fbSRobert Watsonto the corresponding value:
78a889d1fbSRobert Watson.Bl -tag -width Er
79a889d1fbSRobert Watson.It Bq Er EACCES
80a889d1fbSRobert WatsonSearch permission is denied for a component of the path prefix, or the

87a889d1fbSRobert WatsonArgument
88a889d1fbSRobert Watson.Va acl
89a889d1fbSRobert Watsondoes not point to a valid ACL for this object, or the ACL type
90a889d1fbSRobert Watsonspecified in
91a889d1fbSRobert Watson.Va type
92a889d1fbSRobert Watsonis invalid for this object, or both.
