+.SH DESCRIPTION
+The
+.BR libsimple_strcasecmpnul ()
+function compares the strings
+.I a
+and
+.IR b ,
+both of which may be
+.BR NULL ,
+which is treated as less than the empty string.
+.PP
+If one of the strings begins with the other string
+but is longer, the longer string is treated as
+greater than the shorter string.
+.PP
+The comparison is case-insensitive and made as if the
+strings were converted to lowercase and as
+.IR "unsigned char *" s.
+.SH RETURN VALUE
+The
+.BR libsimple_strcasecmpnul ()
+function returns a negative value if
+.I a
+is less than
+.IR b ,
+a positive value if
+.I a
+is greater than
+.IR b ,
+and 0 otherwise.
+.SH ERRORS
+The
+.BR libsimple_strcasecmpnul ()
+function cannot fail.
