DMA_BUF_EXPORT_NAMED(9) Device drivers infrastructure DMA_BUF_EXPORT_NAMED(9)NAMEdma_buf_export_named - 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. Additionally, provide a
name string for exporter; useful in debugging.
SYNOPSIS
struct dma_buf * dma_buf_export_named(void * priv,
const struct dma_buf_ops * ops,
size_t size, int flags,
const char * exp_name);
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.
exp_name
[in] name of the exporting module - useful for debugging.
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.
