◆ Begin()

GLF_API void Begin ( GLenum target )

Begin query for the given target target has to be one of GL_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED, GL_ANY_SAMPLES_PASSED_CONSERVATIVE, GL_PRIMITIVES_GENERATED GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN GL_TIME_ELAPSED, GL_TIMESTAMP.

◆ BeginPrimitivesGenerated()

GLF_API void BeginPrimitivesGenerated ( )

equivalent to Begin(GL_PRIMITIVES_GENERATED).

The number of primitives sent to the rasterizer by the scoped drawing command will be returned.

◆ BeginSamplesPassed()

GLF_API void BeginSamplesPassed ( )

equivalent to Begin(GL_SAMPLES_PASSED).

The number of samples that pass the depth test for all drawing commands within the scope of the query will be returned.

◆ BeginTimeElapsed()

GLF_API void BeginTimeElapsed ( )

equivalent to Begin(GL_TIME_ELAPSED).

The time that it takes for the GPU to execute all of the scoped commands will be returned in nanoseconds.

◆ End()

GLF_API void End ( )

End query.

◆ GetResult()

GLF_API int64_t GetResult ( )

Return the query result (synchronous) stalls CPU until the result becomes available.

◆ GetResultNoWait()

GLF_API int64_t GetResultNoWait ( )

Return the query result (asynchronous) returns 0 if the result hasn't been available.
