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.
       Additionally, provide a name string for exporter; useful in debugging.

SYNOPSIS
       struct dma_buf * dma_buf_export(const struct dma_buf_export_info * exp_info);

ARGUMENTS
       exp_info
           [in] holds all the export related information provided by the exporter. see struct
           dma_buf_export_info for further details.

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.
