There are two patch files in this package.
|
|
slouken@30
|
8 |
|
|
slouken@30
|

1. The first patch file, nanox.patch, is to fix a bug in Nano-X.
|
|
slouken@30
|
10 |
This patch is proposed by Gary James (gjames@twcny.rr.com).
|
|
slouken@30
|
11 |
|
|
slouken@30
|
12 |
It fixes the client side GrClose(). In the original version,
|
|
slouken@30
|
13 |
GrOpen() can only be called once. When the GrOpen() is called at
|
|
slouken@30
|
14 |
the second time, the program will terminate. In order to prevent
|
|
slouken@30
|
15 |
this situation, we need to insert "nxSocket = -1" after
|
|
slouken@30
|
16 |
"close(nxSocket)" in GrClose(). If you do not have this problem,
|
|
slouken@30
|
17 |
you may skip this step.

If the wrong pixel type is used, the program will crash when the
|
|
slouken@30
|
37 |
sub-routine updates the screen. This option depends on SCREEN_PIXTYPE
|
|
slouken@30
|
38 |
which is defined in Microwin0.89pre7/src/config. SCREEN_PIXTYPE
|
|
slouken@30
|
39 |
is used to define the pixel type in Microwindows/Nano-X.
|
|
slouken@30
|
40 |
I only test the program when the pixel type is in "rgb"
|
|
slouken@30
|
41 |
(Microwin under X11) or "888" (framebuffer in 24-bit).
