Code: if we come up with a way to allow the compiler to know which function method is inside ebx, then this will be possible...

Ebx(p1,p2,p3); // default to stdcall Ebx(p1,p2,p3) as cdecl; // self explnaition Emil. http://www.freewebs.com/ogremagic/index.htm |

I will see about adding this for next release. Download Ziron Get free hosting for Ziron related fan-sites and Ziron projects, contact me in private message. |

BTW , this feature will easily calling a function which stored in array , if we have an array which hold a pointers to some functions , so we also do the following. var1 = Ebx[1](par1,par2,par3); // call first function in array pointer. var4 = Ebx[4](par1); // call 4 th function in array pointer. and so on what do you think ?

[ebx+3] .. i will look into that further. meanwhile i have added register calling for next release, however it will be experimental, it will probably need alot of testing for the next few releases. Code: default is stdcall. Download Ziron Get free hosting for Ziron related fan-sites and Ziron projects, contact me in private message. |
