Function provide_buffers [src]

Queues (but does not submit) an SQE to provide a group of buffers used for commands that read/receive data. Returns a pointer to the SQE. Provided buffers can be used in read, recv or recvmsg commands via .buffer_selection. The kernel expects a contiguous block of memory of size (buffers_count * buffer_size).

Prototype

 pub fn provide_buffers( self: *IoUring, user_data: u64, buffers: [*]u8, buffer_size: usize, buffers_count: usize, group_id: usize, buffer_id: usize, ) !*linux.io_uring_sqe

Parameters

self: *IoUringuser_data: u64buffers: [*]u8buffer_size: usizebuffers_count: usizegroup_id: usizebuffer_id: usize
