[Plplot-devel] Correction to commit message

[Alan W. I. <ir...@be...>]

Geoffrey, in case you were worried by my commit message (see below), I have
investigated further, and the problem with the perl script is not that bad.

There are some problems with the wrapper.  For example, I find that e.g.,

plgcol0 1

incorrectly gives wrong number of arguments message rather than simply
printing out the r, g, and b numbers the way that

plgcolbg

does.  Furthermore,

plgcol0

segfaults rather than giving you the wrong number of arguments message.

But if you give every argument, e.g.,

plgcol0 2 r g b

no segfault occurs, and r, g, and b are filled with the correct values.
Thus, I could have used plgcol0 0 r g b to get the background colours, but I
added plgcolbg to the tcl API, instead, and it works fine for my needs.

Subject: [Plplot-cvs] CVS update notice (plplot/bindings/tcl)

Update of /cvsroot/plplot/plplot/bindings/tcl
In directory usw-pr-cvs1:/tmp/cvs-serv4152

Modified Files:
	plapi.tpl
Log Message:
Implemented plgcolbg, and it works well.

Changed plgcol0 to try and get it to work, but it segfaults regardless.
This must be a limitation of the current perl script for generating the
tcl wrapper code from this file.  plgcol0 has one input parameter and
3 returned values, and that must be confusing the perl script.
