Tcl_Init(3) Tcl Library Procedures Tcl_Init(3) ________________________________________________________________________________ NAME Tcl_Init - find and source initialization script SYNOPSIS #include <tcl.h> int Tcl_Init(interp) const char * Tcl_SetPreInitScript(scriptPtr) ARGUMENTS Tcl_Interp *interp (in) Interpreter to initialize. const char *scriptPtr (in) Address of the initialization script. ________________________________________________________________________________ DESCRIPTION Tcl_Init is a helper procedure that finds and sources the init.tcl script, which should exist somewhere on the Tcl library path. Tcl_Init is typically called from Tcl_AppInit procedures. Tcl_SetPreInitScript registers the pre-initialization script and returns the former (now replaced) script pointer. A value of NULL may be passed to not register any script. The pre-initialization script is executed by Tcl_Init before accessing the file system. The purpose is to typically pre- pare a custom file system (like an embedded zip-file) to be activated be- fore the search. When used in stub-enabled embedders, the stubs table must be first initial- ized using one of Tcl_InitSubsystems, Tcl_SetPanicProc, Tcl_FindExecutable or TclZipfs_AppHook before Tcl_SetPreInitScript may be called.
