.TH range_bufinbuf 3
|
|
.SH NAME
|
|
range_bufinbuf \- range check for buf in buffer
|
|
.SH SYNTAX
|
|
.B #include <rangecheck.h>
|
|
|
|
int \fBrange_bufinbuf\fR(const void* buf1,size_t len1,
|
|
const void* buf2,size_t len2);
|
|
|
|
.SH DESCRIPTION
|
|
range_bufinbuf checks that the buffer \fIbuf2\fR[0..\fIlen2\fR-1] lies
|
|
entirely in \fIbuf1\fR[0..\fIlen1\fR].
|
|
|
|
If the buffer is 0-terminated and you don't know the length beforehand,
|
|
use range_strinbuf, range_str2inbuf or range_str4inbuf instead.
|
|
.SH "RETURN VALUE"
|
|
If one of the buffers is implausible (buf is NULL or buf+len has an integer
|
|
overflow), return 0.
|
|
|
|
If the buf2[0..len2-1] lies before or after buf1[0..len1-1], return 0.
|
|
|
|
Otherwise, return 1.
