glInvalidateBufferSubData — invalidate a region of a buffer object's data store
void glInvalidateBufferSubData(
|
GLuint buffer, |
| GLintptr offset, | |
GLsizeiptr length); |
buffer
The name of a buffer object, a subrange of whose data store to invalidate.
offset
The offset within the buffer's data store of the start of the range to be invalidated.
length
The length of the range within the buffer's data store to be invalidated.
glInvalidateBufferSubData invalidates all or part of the
content of the data store of a buffer object. After invalidation, the content
of the specified range of the buffer's data store becomes undefined. The
start of the range is given by offset and its size
is given by length, both measured in basic machine units.
GL_INVALID_VALUE is generated if offset or
length is negative, or if offset +
length is greater than the value of GL_BUFFER_SIZE
for buffer.
GL_INVALID_VALUE is generated if buffer is not the
name of an existing buffer object.
GL_INVALID_OPERATION is generated if any part of buffer
is currently mapped.
