Not 100% clear how to incorporate this into an event loop

[kierank]

You can do callbacks, but what do you poll on and how do you incorporate into an event loop.

Adding these new APIs to support single threaded event loop and thread usage by the underlying API's implementation:

/**
 * @brief Initialize the GCCG transport API. This sets limits on the number of threads and thread priority that the
 * underlying API can use. If this API is not invoked, thread usage within the underlying API is not restricted.
 * 
 * @param maximum_thread_count Maximum number of threads the underlying API can use.
 * @param maximum_thread_priority Maximum thread priority the underlying API can use. The range is 0 (lowest) to
 *                                99 (highest).
 *
 * @return A value from the GccgReturnStatus enumeration.
 */
GCCG_INTERFACE GccgReturnStatus GccgInitialize(int maximum_thread_count, int maximum_thread_priority);

/**
 * @brief Only required when using a single-threaded, event loop to service the API.
 * 
 * @param handle Connection handle returned by one of the create connection functions.
 * 
 * @return A value from the GCCG_INTERFACE enumeration.
 */
GCCG_INTERFACE GccgReturnStatus GccgEventLoopPoll(GccgConnectionHandle handle);
