NAME

SYNOPSIS

ARGUMENTS

Tcl_Interp *interp (in)

Interpreter to initialize.

const char *scriptPtr (in)

Address of the initialization script.

DESCRIPTION

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.
