May 09, 2004 Attributes problems (any ideas for a fix... maybe []?) | ||||
---|---|---|---|---|
| ||||
Attributes are pretty good, but they need another form I need to be able to do version(UseWindowExports) { [extern (Windows):] }else { [extern (C):] } void glStipple (int, short); right now the colon ends at the next closing brace I want it to survive ONE extra closing brace... or until the next attribute. if I take out the closing brace, then I have to write the glStipple (n) times where n is the number of versions of the lib I want to make can anyone help think of some syntax to fix this..it really makes writing cross-platform headers quite unfeasable the way it is. the language needs ways to make cross-platform headers with different linkages specified on a per-version basis... I can't have gl_sgi.h gl_mac.h gl_windows.h gl_linux.h gl_ppclinux.h(different ABI) --Daniel |

I don't think it'll go undefined. However you can try and see what happens. ----------------------- Carlos Santander Bernal |

Posted in reply to Vathix | My first thought is to say this looks like a good idea. But my second thought says that alias is starting to look more and more like a macro language...
