Subject: Fixed service context detection when built with VS2013.
X-Git-Tag: v2.22~31
X-Git-Url: http://git.iain.cx/?p=nssm.git;a=commitdiff_plain;h=997e224304151f2543e6def6f673f1f1a8c9a38c

Fixed service context detection when built with VS2013.

Visual Studio 2013 includes a C runtime which assigns stdin, stdout and
stderr the file descriptors 0, 1 and 2 - just like UNIX does - even if
there are no streams available.  Thus we can no longer use "_fileno(stdin)
< 0" as a check for running in a service context.

Instead we check for "GetStdHandle(STD_INPUT_HANDLE) == 0" which works
when compiled with older or newer versions of Visual Studio.

Thanks Czenda Czendov.
