os.writev()

os.writev(fd, buffers)

Write the contents of buffers to file descriptor fd. buffers must be a sequence of bytes-like objects. Buffers are processed in array order. Entire contents of first buffer is written before proceeding to second, and so on. The operating system may set a limit (sysconf() value SC_IOV_MAX) on the number of buffers that can be used.

writev() writes the contents of each object to the file descriptor and returns the total number of bytes written.
