- This function is deprecated as of Cuda 3.0.
Set flags for mapping the OpenGL buffer
bufObj
Changes to flags will take effect the next time bufObj is mapped. The flags argument may be any of the following:
- cudaGLMapFlagsNone: Specifies no hints about how this buffer will be used. It is therefore assumed that this buffer will be read from and written to by CUDA kernels. This is the default value.
- cudaGLMapFlagsReadOnly: Specifies that CUDA kernels which access this buffer will not write to the buffer.
- cudaGLMapFlagsWriteDiscard: Specifies that CUDA kernels which access this buffer will not read from the buffer and will write over the entire contents of the buffer, so none of the data previously stored in the buffer will be preserved.
If bufObj has not been registered for use with CUDA, then cudaErrorInvalidResourceHandle is returned. If bufObj is presently mapped for access by CUDA, then cudaErrorUnknown is returned.
- Parameters:
-
| bufObj | - Registered buffer object to set flags for |
| flags | - Parameters for buffer mapping |
- Returns:
- cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
