For inline do what lightatdawn shows.
For incorporating pure asm files do this:
ASM file
Code:
.model LARGE
.code
public _Test
_Test PROC
;to pass parameters do the following
ARG x:WORD, y:WORD, z:WORD
;to use local variables by name instead of address do this
LOCAL temp1:WORD,temp2:WORD
;example
;mov ax,x - x refers to WORD x from ARG
;add ax,y - y refers to WORD y from ARG
;mov temp1,ax - can refer to temp1 as a variable
push bp ;do not forget if you use ARG
mov bp,sp ;do not forget if you use ARG
;Do your asm here
pop bp ;do not forget this if you use ARG
ret
_Test ENDP
The ARG directive allows you to access parameters w/o having to worry about the diff memory models - but model has to be large to use ARG. No need to use bp+6, bp+4, etc., when you use ARG.
Other requirement is that you must push bp and mov bp,sp and pop bp before you leave the procedure - otherwise it will crash the system.
Then save the file with your asm functions in it. The extension should be .asm
Include the asm file(s) in your project or their objs. Just include the text version of the asm file and set it's local options to use your assembler instead of the C compiler. This way you can compose assembly and C within the same editor and each program will return what errors occured and show you where they occurred.
Now in C we want to call these just like standard functions:
extern "C"
{
void Test(WORD x,WORD y,WORD z);
//any other asm functions
}
Now you can call your asm Test() from C just like any other C function
If you want to return values from asm functions, C returns values from functions in the AX register.
