+.SH DESCRIPTION
+The
+.BR libsimple_rawmemrcasechr ()
+function scans the memory segment
+.IR s ,
+with the size
+.IR n ,
+for the last occurence of the byte
+.I c
+(it is converted to a
+.BR char ).
+.PP
+The
+.BR libsimple_rawmemrcasechr ()
+function assumes there is at least one
+occurence, its behaviour is undefined
+if this is not the case.
+.PP
+The comparison is case-insensitive.
+.SH RETURN VALUE
+The
+.BR libsimple_rawmemrcasechr ()
+function returns the pointer
+.I s
+with a maximal offset such that
+.IR tolower(*r)==tolower(c) ,
+where
+.I r
+is the returned pointer.
+.SH ERRORS
+The
+.BR libsimple_rawmemrcasechr ()
+function cannot fail.
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see
