| int | is_glx_extension_supported (Display *dpy, const char *query) |
| // ripped off from glxgears.c Determine whether or not a GLX extension is supported. | |
| int | readbytes (const char *fname, char *&buffer) |
| int | readyuvbytes (const char *fname, GLubyte *&Y, GLubyte *&U, GLubyte *&V) |
| Auxiliary routine for testing. | |
| void | zeroyuvbytes (int ysize, GLubyte *&Y, GLubyte *&U, GLubyte *&V) |
| Auxiliary routine for testing. | |
| void | getPBO (GLuint &index, GLsizei size, GLubyte *&payload) |
| Get PBO from the GPU. There are two versions of this function: other one can be enabled in source for valgrind debugging. | |
| void | releasePBO (GLuint *index, GLubyte *payload) |
| void | getTEX (GLuint &index, GLint internal_format, GLint format, GLsizei w, GLsizei h) |
| Get texture from the GPU. | |
