An application is required to perform a successful
SshInitialize call before it can call any of the other library
functions. When it has completed the use of library, the application
must call SshUninitialize to allow the library to free any
resources allocated on behalf of the process. Any pending blocking or
asynchronous calls in this process are canceled without posting any
notification messages, and all sockets that were opened by the
process are closed.
There must be a call to SshUninitialize for every
successful call to SshInitialize made by a process. In a
multithreaded environment, operations for all threads in the client
are terminated.
