+.SH DESCRIPTION
+The
+.BR libsimple_memmem ()
+function scans the memory segment
+.IR haystack ,

+.IR nhaystack ,
+for the first occurence of the byte string
+.I needle
+with the size
+.IR nneedle .
+.PP
+The comparison is case-sensitive.
+.SH RETURN VALUE
+The
+.BR libsimple_memmem ()
+function returns the pointer
+.I s
+with a minimal offset such that
+.IR !memcmp(r,needle,nneedle) ,
+where
+.I r
+is the returned pointer.
+If no such offset exists,
+.B NULL
+is returned.

+The
+.BR libsimple_memmem ()
+function cannot fail.
