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 \fIinterp->result\fR +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. + +.SH KEYWORDS +initialization procedure, package, static linking |
