| Issue |
We want to write an inline assembly code but could not make it work. This function converts a floating point number into a long integer. Here is the code.
long ftol (float v)
{
long rv;
asm
{
fld v
fistp rv
}
return rv;
}
We could not compile it.

| Solution |
The assembly code needs to be all on one line.
You can use the / to make it look like
it is all on one line. Then you need to put the assembly commands between double quotes (") and separated them by a coma (,).
Please look in the helpviewer for more information. The examples can be found in:
