os.readv()

os.readv(fd, buffers)

Read from a file descriptor fd into a number of mutable bytes-like objects buffers. readv() will transfer data into each buffer until it is full and then move on to the next buffer in the sequence to hold the rest of the data. readv() returns the total number of bytes read (which may be less than the total capacity of all the objects).

Availability: Unix.

New in version 3.3.
