+ Scans a target buffer for an 8-bit value, and returns a pointer to the matching 8-bit value
+ in the target buffer.
+
+ This function searches target the buffer specified by Buffer and Length from the lowest
+ address to the highest address for an 8-bit value that matches Value. If a match is found,
+ then a pointer to the matching byte in the target buffer is returned. If no match is found,
+ then NULL is returned. If Length is 0, then NULL is returned.
+ If Length > 0 and Buffer is NULL, then ASSERT().
+ If Length is greater than (MAX_ADDRESS ? Buffer + 1), then ASSERT().
+
+ @param Buffer Pointer to the target buffer to scan.
+ @param Length Number of bytes in Buffer to scan.
+ @param Value Value to search for in the target buffer.
+
+ @return A pointer to the matching byte in the target buffer or NULL otherwise.
