NAME    [Toc]    [Back]

     dmPMGetSourceAUsage, dmPMGetSourceBUsage, dmPMGetDestUsage	- retrieves
     the usage bitmask of the plugin

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/fx_plugin_mgr.h>

     int dmPMGetSourceAUsage
	   ( DMplugin* plugin )

     int dmPMGetSourceBUsage
	   ( DMplugin* plugin )

     int dmPMGetDestUsage
	   ( DMplugin* plugin )

PARAMETERS    [Toc]    [Back]

     plugin   A	pointer	to a DMplugin, which was created with dmPMInitPlugin
	      or dmPMInitDirectory.

DESCRIPTION    [Toc]    [Back]

     dmPMGetSourceAUsage returns the usage bitmask of the source A.  Possible
     values are:

     #define DM_BUF_INPUT_DIRECT       0x0001  /* reads	from void *data	*/
     #define DM_BUF_INPUT_TEXTURE      0x0002  /* uses OpenGL texturing	*/
     #define DM_BUF_INPUT_DRAWPIXELS	    0x0004  /* uses OpenGL pixel
     drawing */	#define	DM_BUF_INPUT_MOVIE	  0x0008  /* used only by
     application */ #define DM_BUF_INPUT_ALL	 0xFFFF	 /* may	use any	kind
     of	input */


     DM_BUF_INPUT_DIRECT	 reads from void *data

     DM_BUF_INPUT_TEXTURE	 uses OpenGL texturing

     DM_BUF_INPUT_DRAWPIXELS	 uses OpenGL pixel drawing

     DM_BUF_INPUT_MOVIE		 used only by application

     DM_BUF_INPUT_ALL		 may use any kind of input


     dmPMGetSourceBUsage returns the usage bitmask of the source B (video
     transitions only).	 Possible values are:

     DM_BUF_INPUT_DIRECT	 reads from void *data

     DM_BUF_INPUT_TEXTURE	 uses OpenGL texturing

     DM_BUF_INPUT_DRAWPIXELS	 uses OpenGL pixel drawing

     DM_BUF_INPUT_MOVIE		 used only by application

     DM_BUF_INPUT_ALL		 may use any kind of input


     dmPMGetDestUsage returns the usage	bitmask	of the destination.  Possible
     values are:


     DM_BUF_OUTPUT_DIRECT     writes to	void *data

     DM_BUF_OUTPUT_OPENGL     renders with OpenGL

     DM_BUF_OUTPUT_MOVIE      used only	by application

CAVEATS    [Toc]    [Back]

     Calling dmPMGetSourceAUsage, dmPMGetSourceBUsage, or dmPMGetDestUsage
     will cause	the plugin to be loaded	with dlopen(3) if it is	not already
     loaded.

RETURN VALUES    [Toc]    [Back]

     dmPMGetSourceAUsage will return the usage bitmask of the source A.
     dmPMGetSourceBUsage will return the usage bitmask of the source B.
     dmPMGetDestUsage will return the the usage	bitmask	of the destination.
