C function become a tcl Command

[mistkhan]

I wanted to write a C code which will program a flash. This should happen on selection of a button in a GUI. ie calling this flash C function from tcl/tk. For this should I have to create tcl command using tclCreateCommand , tclInterp... Like this I have lots of device program and application which is in C. For all these things should I have to create a tclCreateCommand. According to my understanding all the C function will become a tcl Command ?. Is this right.

Thanking you in advance

General speaking, yes. But I've got two ideas for you that might save you a lot of effort that you can explore more on the Tcl'ers Wiki (

http://wiki.tcl.tk):

If you've got existing C code -- or even a compiled library for which you have header files -- SWIG can automatically generate all the wrapper code you need to expose those C functions as Tcl commands. Highly recommended for situations like these. Check it out at

If you're writing the C code from scratch, you might consider using Critcl, which in essence allows you to embed C code directly in your Tcl scripts. Read more about it at

Don't understand why you want a C nightmare to flash a button.
It's easy to let Tcl & Tk do the job.
(maybe I don't understand what you want to do)

I suspect that Aman wants to progam a flash memory device, though I could be mistaken.
