- Scans a target buffer for a 32-bit value, and returns a pointer to the matching 32-bit value\r
- in the target buffer.\r
-\r
- This function searches target the buffer specified by Buffer and Length from the lowest\r
- address to the highest address for a 32-bit value that matches Value. If a match is found,\r
- then a pointer to the matching byte in the target buffer is returned. If no match is found,\r
- then NULL is returned. If Length is 0, then NULL is returned.\r
- If Length > 0 and Buffer is NULL, then ASSERT().\r
- If Buffer is not aligned on a 32-bit boundary, then ASSERT().\r
- If Length is not aligned on a 32-bit boundary, then ASSERT().\r
- If Length is greater than (MAX_ADDRESS ? Buffer + 1), then ASSERT(). \r

- @param Buffer Pointer to the target buffer to scan.\r
- @param Length Number of bytes in Buffer to scan.\r
- @param Value Value to search for in the target buffer.\r

- @return A pointer to the matching byte in the target buffer or NULL otherwise.\r
