Finds the first control that can open a file in a given mode
#include <aoi.h> AOIStream_t *AoOpenFilespec(const char *filename, const char *mode);
This function iterates through all the available addons (addons that have been added using an AoAdd*() function) that export a AOIStreamer interface and returns the AOIStream_t for the first addon that successfully opens the given filespec in the given mode. In this case, the control element of the AOIStream_t structure is filled in with the control, and the control is held. When the stream has been closed, you should release this control.
A pointer to an AOIStream_t for the successfully opened stream, orNULL if no streamer addons are found.
