Function recv [src]

Queues (but does not submit) an SQE to perform a recv(2). Returns a pointer to the SQE. Available since 5.6

Prototype

pub fn recv( self: *IoUring, user_data: u64, fd: posix.fd_t, buffer: RecvBuffer, flags: u32, ) !*linux.io_uring_sqe

Parameters

self: *IoUringuser_data: u64fd: posix.fd_tbuffer: RecvBufferflags: u32
