Inside a plugin I call Console_Input via inline assembler, the generated call is:

call    near ptr __imp_?Console_Input@@YAXPBD@Z ; Console_Input(char const *)


However, when I call that function using the normal (non-assembler) syntax, the following call is generated:

call    ds:__imp_?Console_Input@@YAXPBD@Z ; Console_Input(char const *)


If I wrap Console_Input() inside another function in my plugin and call that wrapper instead, it works correctly, I'm using the following assembler code to call Console_Input():

call Console_Input


Any suggestions? The call that's generated for the assembler code causes the fds to crash.

We have run into this problem before in scripts, the simple answer is that you cant call a function that's imported from another dll inside an ASM block (at least we never found such a way)
Thats why the HookupAT3x function exists in all the SSGM plugins.
