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  over-
       flows), return 0.

       If the first or last element of the array points before or after the buffer, return 0.

       Otherwise, return 1.
