+.SH DESCRIPTION
+Like
+.BR access (),
+.BR euidaccess ()
+checks permissions and existence of the file identified by its argument

+uses the effective identifiers.
+

+is a mask consisting of one or more of
+.BR R_OK ", " W_OK ", " X_OK " and " F_OK ,
+with the same meanings as for 
+.BR access ().
+
+.BR eaccess ()
+is a synonym for
+.BR euidaccess (),
+provided for compatibility with some other systems.
+.SH "RETURN VALUE"
+On success (all requested permissions granted), zero is returned.
+On error (at least one bit in
+.I mode
+asked for a permission that is denied, or some other error occurred),
+\-1 is returned, and
+.I errno
+is set appropriately.
+.SH ERRORS
+As for
+.BR access ().
