+ * Initialize the OpenSSL locks
+ *
+ * OpenSSL requires the application to determine how it performs
+ * locking.
+ *
+ * This is a last-resort convenience function which libgit2 provides for
+ * allocating and initializing the locks as well as setting the
+ * locking function to use the system's native locking functions.
+ *
+ * The locking function will be cleared and the memory will be freed
+ * when you call git_threads_sutdown().
+ *
+ * If your programming language has an OpenSSL package/bindings, it
+ * likely sets up locking. You should very strongly prefer that over
+ * this function.
+ *
+ * @return 0 on success, -1 if there are errors or if libgit2 was not
+ * built with OpenSSL and threading support.
