/**
 * 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.
 *
 * Returns: 0 on success, -1 if there are errors or if libgit2 was not built with OpenSSL and threading support.
