NAME
Tcl_InitSubsystems - initialize the Tcl library.
SYNOPSIS
#include <tcl.h>
const char *
Tcl_InitSubsystems()
_________________________________________________________________
DESCRIPTION
The Tcl_InitSubsystems procedure initializes the Tcl library. This procedure is typically invoked as the
very first thing in the application's main program.
The result of Tcl_InitSubsystems is the full Tcl version with build information (e.g.,
9.0.0+abcdef...abcdef.gcc-1002).
Tcl_InitSubsystems is very similar in use to Tcl_FindExecutable. It can be used when Tcl is used as
utility library, no other encodings than utf-8, iso8859-1 or utf-16 are used, and no interest exists in
the value of info nameofexecutable. The system encoding will not be extracted from the environment, but
falls back to utf-8.
