bson/bson-context.c  view on Meta::CPAN

 *       Initializes a new context with the flags specified.
 *
 *       In most cases, you want to call this with @flags set to
 *       BSON_CONTEXT_NONE.
 *
 *       If you are running on Linux, %BSON_CONTEXT_USE_TASK_ID can result
 *       in a healthy speedup for multi-threaded scenarios.
 *
 *       If you absolutely must have a single context for your application
 *       and use more than one thread, then %BSON_CONTEXT_THREAD_SAFE should
 *       be bitwise-or'd with your flags. This requires synchronization
 *       between threads.
 *
 *       If you expect your hostname to change often, you may consider
 *       specifying %BSON_CONTEXT_DISABLE_HOST_CACHE so that gethostname()
 *       is called for every OID generated. This is much slower.
 *
 *       If you expect your pid to change without notice, such as from an
 *       unexpected call to fork(), then specify
 *       %BSON_CONTEXT_DISABLE_PID_CACHE.
