range_arrayinbuf(3) Library Functions Manual range_arrayinbuf(3) NAME range_arrayinbuf - range check for array in buffer SYNTAX #include <libowfat/rangecheck.h> int range_arrayinbuf(const void* buf,size_t len, const void* arraystart, size_t elements,size_t membersize); DESCRIPTION range_arrayinbuf checks that the array starting at arraystart consisting of elements members of size membersize each starts and ends within the buffer buf[0..len-1]. If the array is 0-terminated and you don't know the length beforehand, use range_strinbuf, range_str2inbuf or range_str4inbuf instead. RETURN VALUE If the buffer is implausible (buf is NULL or buf+len has an integer over- flow), return 0. If the array is implausible (arraystart is NULL, elements*membersize over- flows, or calculating the byte offset of the last element overflows), re- turn 0. If the first or last element of the array points before or after the buffer, return 0. Otherwise, return 1. SEE ALSO rangecheck(3) range_arrayinbuf(3)
