Hello,

Is there a way from D to do this, without writing a C wrapper?

e.g. I want to call a C function named 'try'.

/* C prototype */
int try(int x);

//D that doesn't work:
extern(C) int try(int x);

Try:

pragma(mangle, "try")
extern(C) int try_(int x);

then call it with the udnerscore in D, the linker should tie it 
up thanks to the pragma.
