DMA_BUF_EXPORT(9) Device drivers infrastructure DMA_BUF_EXPORT(9)

NAME dma_buf_export - Creates a new dma_buf, and associates an anon file with this buffer, so it can be exported. Also connect the allocator specific data and ops to the buffer.

SYNOPSIS struct dma_buf * dma_buf_export(void * priv, const struct dma_buf_ops * ops, size_t size, int flags);

ARGUMENTS priv [in] Attach private data of allocator to this buffer

ops [in] Attach allocator-defined dma buf ops to the new buffer.

size [in] Size of the buffer

flags [in] mode flags for the file.

DESCRIPTION Returns, on success, a newly created dma_buf object, which wraps the supplied private data and operations for dma_buf_ops. On either missing ops, or error in allocating struct dma_buf, will return negative error.
