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 prepare a custom file system (like an embedded zip-file) to be activated before the search.
When used in stub-enabled embedders, the stubs table must be first initialized using one of Tcl_InitSubsystems, Tcl_SetPanicProc, Tcl_FindExecutable or TclZipfs_AppHook before Tcl_SetPreInitScript may be called.
