.SH DESCRIPTION
rangecheck.h provides several routines for range checking pointers.
These routines are meant for code that has to validate the syntax and
semantics of buffers coming in from untrusted sources (like a network
connection or an input file).

.SH "RETURN VALUE"
The routines all return 0 on error, or 1 if the pointers were in range.

.SH "SEE ALSO"
range_validbuf(3), range_ptrinbuf(3), range_bufinbuf(3),
range_arrayinbuf(3), range_strinbuf(3), range_str2inbuf(3),
range_str4inbuf(3)
