Hi!!! 
I have my source code in MS C. Now I need use VC 
&nbsp; &nbsp; My Source code compile OK (only 1 warning), but Link &nbsp;and received the following: 
 
&nbsp; &nbsp; Timer.obj : error LNK2001: unresolved external symbol _IntSvcRtn 
&nbsp; &nbsp; Timer.obj : error LNK2001: unresolved external symbol _wCount 
&nbsp; &nbsp; ......... 
&nbsp; &nbsp; .... another 
 
&nbsp; &nbsp; IntSvcRtn function is under a &nbsp;.asm source code file, I use 
&nbsp; &nbsp; #pragma alloc_text(FIXED_TEXT,IntSvcRtn) function C 
 
&nbsp; &nbsp; Source code .asm file is: 
&nbsp; &nbsp; .... 
&nbsp; &nbsp; FIXED_DATA SEGMENT DWORD PUBLIC 'DATA' 
&nbsp; &nbsp; .... 
&nbsp; &nbsp; .... 
&nbsp; &nbsp; FIXED_TEXT SEGMENT PARA PUBLIC 'CODE' 
&nbsp; &nbsp; selData1 &nbsp; &nbsp;dw FIXED_DATA 
&nbsp; &nbsp; assume CS:FIXED_TEXT,DS:NOTHING 
&nbsp; &nbsp; PUBLIC _IntSvcRtn 
&nbsp; &nbsp; _IntSvcRtn label far 
&nbsp; &nbsp; &nbsp;IntSvcRtn proc far 
&nbsp; &nbsp; sub sp,4 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .... 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .... 
 
&nbsp; &nbsp; What's Up?? 
&nbsp; &nbsp; I need Porting my MS C code (32bits) to MS Visual C 5.0 (32bits). 
 
&nbsp; &nbsp; What I can do?? any Idea?? &nbsp; 
 
&nbsp; &nbsp; Thanks Again!! 
&nbsp; &nbsp; Sincerely.

Porting MS C to MS Visual C

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
