Detailed Description

Enumeration Type Documentation
enum cudaGLMapFlags
CUDA GL Map Flags
Enumerator:
cudaGLMapFlagsNone
Default; Assume resource can be read/written
cudaGLMapFlagsReadOnly
CUDA kernels will not write to this resource
cudaGLMapFlagsWriteDiscard
CUDA kernels will only write to and will not read from this resource
Function Documentation
__CUDA_DEPRECATED cudaError_t cudaGLMapBufferObject (void ** devPtr, GLuint bufObj)
Deprecated
This function is deprecated as of CUDA 3.0.
Maps the buffer object of ID bufObj into the address space of CUDA and returns in *devPtr the base
pointer of the resulting mapping. The buffer must have previously been registered by calling
cudaGLRegisterBufferObject(). While a buffer is mapped by CUDA, any OpenGL operation which references the
buffer will result in undefined behavior. The OpenGL context used to create the buffer, or another
context from the same share group, must be bound to the current thread when this is called.
All streams in the current thread are synchronized with the current GL context.
Parameters:
devPtr - Returned device pointer to CUDA object
bufObj - Buffer object ID to map
Returns:
cudaSuccess, cudaErrorMapBufferObjectFailed
Note:
Note that this function may also return error codes from previous, asynchronous launches.

__CUDA_DEPRECATED cudaError_t cudaGLMapBufferObjectAsync (void ** devPtr, GLuint bufObj, cudaStream_t stream)
Deprecated
This function is deprecated as of CUDA 3.0.
Maps the buffer object of ID bufObj into the address space of CUDA and returns in *devPtr the base
pointer of the resulting mapping. The buffer must have previously been registered by calling
cudaGLRegisterBufferObject(). While a buffer is mapped by CUDA, any OpenGL operation which references the
buffer will result in undefined behavior. The OpenGL context used to create the buffer, or another
context from the same share group, must be bound to the current thread when this is called.
Stream /p stream is synchronized with the current GL context.
Parameters:
devPtr - Returned device pointer to CUDA object
bufObj - Buffer object ID to map
stream - Stream to synchronize
Returns:
cudaSuccess, cudaErrorMapBufferObjectFailed
Note:
Note that this function may also return error codes from previous, asynchronous launches.

__CUDA_DEPRECATED cudaError_t cudaGLRegisterBufferObject (GLuint bufObj)
Deprecated
This function is deprecated as of CUDA 3.0.
Registers the buffer object of ID bufObj for access by CUDA. This function must be called before CUDA can
map the buffer object. The OpenGL context used to create the buffer, or another context from the same
share group, must be bound to the current thread when this is called.
Parameters:
bufObj - Buffer object ID to register
Returns:
cudaSuccess, cudaErrorInitializationError
Note:
Note that this function may also return error codes from previous, asynchronous launches.
See also:
cudaGraphicsGLRegisterBuffer
__CUDA_DEPRECATED cudaError_t cudaGLSetBufferObjectMapFlags (GLuint bufObj, unsigned int flags)
Deprecated
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.

__CUDA_DEPRECATED cudaError_t cudaGLSetGLDevice (int device)
Deprecated
This function is deprecated as of CUDA 5.0.
This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA
device with an OpenGL context in order to achieve maximum interoperability performance.
Parameters:
device - Device to use for OpenGL interoperability
Returns:
cudaSuccess, cudaErrorInvalidDevice, cudaErrorSetOnActiveProcess
Note:
Note that this function may also return error codes from previous, asynchronous launches.

cudaGraphicsGLRegisterBuffer, cudaGraphicsGLRegisterImage
__CUDA_DEPRECATED cudaError_t cudaGLUnmapBufferObject (GLuint bufObj)
Deprecated
This function is deprecated as of CUDA 3.0.
Unmaps the buffer object of ID bufObj for access by CUDA. When a buffer is unmapped, the base address
returned by cudaGLMapBufferObject() is invalid and subsequent references to the address result in
undefined behavior. The OpenGL context used to create the buffer, or another context from the same share
group, must be bound to the current thread when this is called.
All streams in the current thread are synchronized with the current GL context.
Parameters:
bufObj - Buffer object to unmap
Returns:
cudaSuccess, cudaErrorUnmapBufferObjectFailed
Note:
Note that this function may also return error codes from previous, asynchronous launches.

cudaGraphicsUnmapResources
__CUDA_DEPRECATED cudaError_t cudaGLUnmapBufferObjectAsync (GLuint bufObj, cudaStream_t stream)
Deprecated
This function is deprecated as of CUDA 3.0.
Unmaps the buffer object of ID bufObj for access by CUDA. When a buffer is unmapped, the base address
returned by cudaGLMapBufferObject() is invalid and subsequent references to the address result in
undefined behavior. The OpenGL context used to create the buffer, or another context from the same share
group, must be bound to the current thread when this is called.
Stream /p stream is synchronized with the current GL context.
Parameters:
bufObj - Buffer object to unmap
stream - Stream to synchronize
Returns:
cudaSuccess, cudaErrorUnmapBufferObjectFailed
Note:
Note that this function may also return error codes from previous, asynchronous launches.
See also:
cudaGraphicsUnmapResources
__CUDA_DEPRECATED cudaError_t cudaGLUnregisterBufferObject (GLuint bufObj)
Deprecated
This function is deprecated as of CUDA 3.0.
Unregisters the buffer object of ID bufObj for access by CUDA and releases any CUDA resources associated
with the buffer. Once a buffer is unregistered, it may no longer be mapped by CUDA. The GL context used
to create the buffer, or another context from the same share group, must be bound to the current thread
when this is called.
Parameters:
bufObj - Buffer object to unregister
Returns:
cudaSuccess
Note:
Note that this function may also return error codes from previous, asynchronous launches.
