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 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
       overflow), return 0.

       If the array is implausible (arraystart is NULL, elements*membersize
       overflows, or calculating 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.
