Using File Descriptors in Python's os Module

• tcgetpgrp(fd): Returns the process group associated with the control terminal associated with fd. (Unix only)
• tcsetpgrp(fd, pg): Sets the process group associated with the control terminal associated with fd. (Unix only)
• ttyname(fd): Returns a string specifying the terminal associated with fd. If no such terminal exists, an OSError exception is raised. (Unix only)
• write(fd, str): Writes str as a string to the file whose file descriptor is fd. Returns the number of bytes written. This is particularly useful if the connection is interrupted due to a network problem or a full disk.
