Currently only a limited set of types of C variable may be linked to using Tcl_LinkVar. This TIP proposes extending this to cover all the basic numeric C types.
With the current implementation it is not possible to link the following types directly to a Tcl variable, making it much more difficult to couple such variables to the Tcl level (compared with int or double variables). This TIP fixes this, making it easier to link C variables and embedded Tcl code.
char
unsigned char
short
unsigned short
unsigned int
long
unsigned long
Tcl_WideUInt
float
There will be no impact on current applications.
The new types are inserted as new #define TCL_LINK_* statements in the tcl.h header file and in the switch statements in the Tcl_Link functions.
The documentation of Tcl_*Link* should mention the new types.
A reference implementation is available as Patch #1242844 on SourceForge[1].
