plP_getinitdriverlist: Get the initialized-driver list

Get the initialized-driver list. Function returns a space-delimited list of the currently initialized drivers or streams. If more than one stream is using the same driver, then its name will be returned more than once. The function can be analogously thought of as also returning the names of the active streams. Invoked internally by plP_checkdriverinit.

text_buffer (char *, output) Pointer to a user-allocated buffer to hold the result. The user must ensure the buffer is big enough to hold the result.
