Write data to the file descriptor
fd_write (
fd: i32The file descriptor (opened with writing permission) to write toiovs: i32A wasm pointer to an array of iovec structures, each describing a buffer to write data fromiovs_len: i32The length of the iovs arraynwritten: i32A wasm pointer to an offset value where the number of bytes written will be written
) =>
error: i32
