| | | | | | | | | | | | | | | | | | | | | | | | be used Tcl_ObjPrintf(), but only in sprintf(). That's unfortunate, clearly an oversight in TIP #237. Conclusion: new TIP must be written to correct this. I'll read a TIP and see what case you have, but TCL_LL_MODIFIER was never meant to play any role in [format] or in Tcl_ObjPrintf(). TCL_LL_MODIFIER exists to help deal with platform differences in sprintf() calls. Tcl_ObjPrintf() in contrast ought to be consistent in its behavior across platforms and should not need such things. If that's false, then fixes to Tcl_ObjPrintf() are in order.
