[Gimp-developer] calling a procedure in a plugin

[Giuseppe Pasquino]

Hello, I'm working on this plugin:
after few operations, it picks a color from the image (with che function gimp_pixel_rgn_get_pixel) to get the guchar value of the components of the related color.
At this point, I need to call the "gimp_by_color_select" procedure but I'm not sure to follow the right way... Anyone can help me? 
How do I  manage the guchar values  to convert in GimpRGB?

Thanks a lot to all and sorry for my bad English (I'm italian)...

Giuseppe.
