 .SH NAME
 Tcl_StaticPackage \- make a statically linked package available via the \fBload\fR command
 .SH SYNOPSIS
 .nf
 \fB#include <tcl.h>\fR
 .sp
 \fBTcl_StaticPackage\fR(\fIinterp, pkgName, initProc, safeInitProc\fR)
 .SH ARGUMENTS
 .AS Tcl_PackageInitProc *safeInitProc
 .AP Tcl_Interp *interp in
 If not NULL, points to an interpreter into which the package has
 already been loaded (i.e., the caller has already invoked the
 appropriate initialization procedure).  NULL means the package
 hasn't yet been incorporated into any interpreter.
 .AP "CONST char" *pkgName in
 Name of the package;  should be properly capitalized (first letter
 upper-case, all others lower-case).
 .AP Tcl_PackageInitProc *initProc in
 Procedure to invoke to incorporate this package into a trusted
 interpreter.
 .AP Tcl_PackageInitProc *safeInitProc in
 Procedure to call to incorporate this package into a safe interpreter
 (one that will execute untrusted scripts).   NULL means the package
 can't be used in safe interpreters.
 .BE

 .SH DESCRIPTION
 .PP
 This procedure may be invoked to announce that a package has been
 linked statically with a Tcl application and, optionally, that it
 has already been loaded into an interpreter.
 Once \fBTcl_StaticPackage\fR has been invoked for a package, it
 may be loaded into interpreters using the \fBload\fR command.
 \fBTcl_StaticPackage\fR is normally invoked only by the \fBTcl_AppInit\fR
 procedure for the application, not by packages for themselves
 (\fBTcl_StaticPackage\fR should only be invoked for statically
 loaded packages, and code in the package itself should not need
 to know whether the package is dynamically or statically loaded).
 .PP
 When the \fBload\fR command is used later to load the package into
 an interpreter, one of \fIinitProc\fR and \fIsafeInitProc\fR will
 be invoked, depending on whether the target interpreter is safe
 or not.
 \fIinitProc\fR and \fIsafeInitProc\fR must both match the
 following prototype:
 .CS
 typedef int Tcl_PackageInitProc(Tcl_Interp *\fIinterp\fR);
 .CE
 The \fIinterp\fR argument identifies the interpreter in which the package
 is to be loaded.  The initialization procedure must return \fBTCL_OK\fR or
 \fBTCL_ERROR\fR to indicate whether or not it completed successfully; in
 the event of an error it should set the interpreter's result to point to an
 error message.  The result or error from the initialization procedure will
 be returned as the result of the \fBload\fR command that caused the
 initialization procedure to be invoked.
