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 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.
