NAME
range_bufinbuf - range check for buf in bufferSYNTAX
#include <rangecheck.h> int range_bufinbuf(const void* buf1,size_t len1, const void* buf2,size_t len2);DESCRIPTION
range_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_strin‐ buf, 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.SEE ALSO
