range_bufinbuf(3)range_bufinbuf(3)NAMErange_bufinbuf - range check for buf in buffer
SYNTAX
#include <rangecheck.h>
int range_bufinbuf(const void* buf1,size_t len1,
const void* buf2,size_t len2);
DESCRIPTIONrange_bufinbuf checks that the buffer buf2[0..len2-1] lies entirely in
buf1[0..len1].
If the buffer is 0-terminated and you don't know the length beforehand,
use range_strinbuf, range_str2inbuf or range_str4inbuf instead.
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.
