Detailed Description

This source file contains the implementation of network interaction functions related to the UDP network fake for tftpfs testing.

The UDP Network Fake requires interactions between TFTP client and test (which emulates a TFTP server). The idea is that each test defines a sequence of interactions. In a successful test run all interactions must be carried out one-by-one till the last interaction is reached.

Interactions appear when the TFTP client calls functions like sendto(), recvfrom(), or socket(). Here functions are defined which

• handle such interactions and
• permit the tests to easily defined the sequence of interactions.
