Combining C & Assembly

Vasavi Chaganti

Can anybody tell me how to combine both C and assembly in Uvision 3?
I know something like we have to use SRC directive,asm and endasm for assembly. Suppose i want to perform some addition operation in assembly and i want to print the result using printf statement in C.How to get the register values to C variables?

    //C style code
#pragma asm
;
;assembly code
;
#pragma endasm
//c style code
    That would be Inline Assembler in a 'C' source file.

    It's almost always better to have separate 'C' and assembler source files, and do the 'C' stuff properly in 'C', and the assembler stuff properly in assembler.
