Constructor
CoglAttributeBuffernew
Declaration [src]
CoglAttributeBuffer*
cogl_attribute_buffer_new (
CoglContext* context,
size_t bytes,
void* data
)
Description [src]
Describes a new CoglAttributeBuffer of size bytes to contain
arrays of vertex attribute data and also uploads size bytes read
from data to the new buffer.
You should never pass a NULL data pointer.
This function does not report out-of-memory errors back to
the caller by returning NULL and so you can assume this function
always succeeds.
In the unlikely case that there is an out of memory problem
then Cogl will abort the application with a message. If your
application needs to gracefully handle out-of-memory errors then
you can use cogl_attribute_buffer_new_with_size() and then
explicitly catch errors with cogl_buffer_set_data() or cogl_buffer_map().
Parameters
context-
Type:
CoglContextA
CoglContext.The data is owned by the caller of the function. bytes-
Type:
size_tThe number of bytes to allocate for vertex attribute data.
data-
Type: An array of
guint8An optional pointer to vertex data to upload immediately.
The length of the array is specified in the bytesargument.The data is owned by the caller of the function.
Return value
Type: CoglAttributeBuffer
A newly allocated CoglAttributeBuffer (never NULL).
| The caller of the function takes ownership of the data, and is responsible for freeing it. |
