GLFLUSH(3G) GLFLUSH(3G)
NAME
glFlush - force execution of GL commands in finite time
C SPECIFICATION
void glFlush( void )
DESCRIPTION
Different GL implementations buffer commands in several different locations, including network
buffers and the graphics accelerator itself. glFlush empties all of these buffers, causing all
issued commands to be executed as quickly as they are accepted by the actual rendering engine.
Though this execution may not be completed in any particular time period, it does complete in finite
time.
Because any GL program might be executed over a network, or on an accelerator that buffers commands,
all programs should call glFlush whenever they count on having all of their previously issued com-mands commands
mands completed. For example, call glFlush before waiting for user input that depends on the gener-ated generated
ated image.
NOTES
glFlush can return at any time. It does not wait until the execution of all previously issued GL
commands is complete.
ERRORS
GL_INVALID_OPERATION is generated if glFlush is executed between the execution of glBegin and the
corresponding execution of glEnd.
