+Btree-source-code
+=================
+
+A working project for High-concurrency B-tree source code in C
+
+There are three major code sets in the btree source code:
+
+btree2q.c Single Threaded/MultiProcess with latching supplied by advisory file locking. Works with network file systems.
+threads2h.c Multi-Threaded/Multi-Process with latching implemented with test & set locks in the btree pages.
+
+The Foster set includes three types of latching:
+
+Fosterbtreee.c Multi-Threaded/Single Process with latches hosted by the buffer pool manager
+Fosterbtreef.c Multi-Threaded/Multi-Process with latches hosted by a latch manager using the first few pages of the btree.
+Fosterbtreeg.c Multi-Threaded/Multi-Process with latches implemented with test & set locks in the btree pages.
+
+Compilation is achieved on linux or Windows by:
+
+gcc -D STANDALONE threads2h.c -lpthread
+
+or
+
+cl /D STANDALONE threads2h.c
