NAME range_arrayinbuf - range check for array in buffer
SYNTAX #include <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 mem‐ bers 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 overflow), return 0. If the array is implausible (arraystart is NULL, elements*membersize overflows, or calcu‐ lating the byte offset of the last element overflows), return 0. If the first or last element of the array points before or after the buffer, return 0. Otherwise, return 1.
