29 Scans a target buffer for an 8-bit value, and returns a pointer to the matching 8-bit value\r
30 in the target buffer.\r
31\r
32 This function searches target the buffer specified by Buffer and Length from the lowest\r
33 address to the highest address for an 8-bit value that matches Value. If a match is found,\r
34 then a pointer to the matching byte in the target buffer is returned. If no match is found,\r
35 then NULL is returned. If Length is 0, then NULL is returned.\r

c5ecf6c1 37 If Length > 0 and Buffer is NULL, then ASSERT().\r
eb1c78db 38 If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().\r
