+.TH LIBSIMPLE_STRNCHR_INV 3 2018-11-25 libsimple
+.SH NAME
+libsimple_strnchr_inv \- find a different character in a string

+.SH DESCRIPTION
+The
+.BR libsimple_strnchr_inv ()
+function scans the string
+.IR s ,
+truncated to
+.I n
+bytes unless it is shorter,
+for the first occurence of any character
+other than

+If no such character exist in the string,
+the string's end is returned.
+.PP
+The comparison is case-sensitive.
+.SH RETURN VALUE
+The
+.BR libsimple_strnchr_inv ()
+function returns the pointer
+.I s
+with a minimal offset such that
+.IR *r!=c ,
+where
+.I r
+is the returned pointer, if no such
+offset less than
+.I n
+exists, it returns
+.BR NULL .
+.SH ERRORS
+The
