Is this a function - or is this a variable?

See pub.mod/glew.mod/glew.bmx


Global glCopyTexSubImage3D(target_:Int,level_:Int,xoffset_:Int,yoffset_:Int,zoffset_:Int,x_:Int,y_:Int,width_:Int,height_:Int)="__glewCopyTexSubImage3D"

Ok this was a function-pointer.



but what is this:

Global GL_VERSION_1_1:Byte="__GLEW_VERSION_1_1"

i think this is a byte pointer - and that was set to __GLEW_VERSION_1_1


is this true?

if i call

print GL_VERSION_1_1
this works

but

print GL_VERSION_1_1()
do not work, so i think that this is not a function...

it looks to be a string of bytes. ie a cstring (ie ansicode uses a byte per character), since blitzmax's normal strings a wstring. (ie unicode, uses a short per character).

cause if it was a byte ptr you wouldn't be able to set it to equal a string.

Global GL_VERSION_1_1:Byte="__GLEW_VERSION_1_1"

work only inside extern-blocks. in normal sources this produce a error-message
