.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.TH Tcl_InitSubsystems 3tcl 8.7 Tcl "Tcl Library Procedures"
.BS
.SH NAME
Tcl_InitSubsystems \- initialize the Tcl library.
.SH SYNOPSIS
.nf
\fB#include <tcl.h>\fR
.sp
const char *
\fBTcl_InitSubsystems\fR(\fIvoid\fR)
.SH DESCRIPTION
.PP
The \fBTcl_InitSubsystems\fR procedure initializes the Tcl
library. This procedure is typically invoked as the very
first thing in the application's main program.
.PP
The result of \fBTcl_InitSubsystems\fR is the full Tcl version with
build information (e.g., \fB9.0.0+abcdef...abcdef.gcc-1002\fR).
.PP
\fBTcl_InitSubsystems\fR is very similar in use to
\fBTcl_FindExecutable\fR. 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 \fBinfo nameofexecutable\fR. The system encoding will not
be extracted from the environment, but falls back to utf-8.
.SH KEYWORDS
binary, executable file
