.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.
|
||
|
|
|
||
|
|
