+  Scans a target buffer for a 64-bit value, and returns a pointer to the\r
+  matching 64-bit value in the target buffer.\r
+\r
+  This function searches target the buffer specified by Buffer and Length from\r
+  the lowest address to the highest address at 64-bit increments for a 64-bit\r
+  value that matches Value. If a match is found, then a pointer to the matching\r
+  value in the target buffer is returned. If no match is found, then NULL is\r
+  returned. If Length is 0, then NULL is returned.\r
+\r
+  If Buffer is NULL, then ASSERT().\r
+  If Buffer is not aligned on a 64-bit boundary, then ASSERT().\r
+  If Length is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().\r

+\r
