NAME: WNetFormatNetworkNameW
SYNOPSIS: Private Shell API for getting the formatted network name
Unicode version
ENTRY: lpProvider - Name of network provider
lpRemoteName - Remote name to format
lpFormattedName - Buffer to receive name
lpnLength - size of lpFormattedName buffer
dwFlags - Formatting flags
dwAveCharePerLine - Avg. characters per line
NOTES: Since this is an unpublished API, we don't do as much
parameter validation as we would for a published API. Also,
since the shell calls this thousands of times to display
things in the Network Neighborhood, we optimize for speed
of the success case.
