NAME: InitializeSockets

SYNOPSIS: Initializes socket access. Among other things, this

|
routine is responsible for connecting to WinSock,

RETURNS: APIERR - NO_ERROR if successful, otherwise a Win32
|
||
|
|
error code.
|
||
|
|
|
||
|
|
NOTES: This routine may only be called by a single thread
|
||
|
|
of execution; it is not necessarily multi-thread safe.

If Val is found, a pointer to Val is
