Hi.

I know this isn't the best place to put this but I thought I'd put it here since this is related to OS development for me.

What I want to do, for example, is move the information from eax into a variable defined in C. How would I do this properly? Basically what I want to do is move data from a register into a C variable.

I've tried several ways which were messy since I don't grasp the GCC inline syntax very well. The times I tried and got the C file to compile, it failed when I linked them into the bin.

Thank you,

Move to a decent compiler with decent inline assembly support - vc2003 toolkit is free

I work with inline assembler not long ago, but I think the following example help you:

#include <stdio.h>

int main(void)
{
unsigned int result;

__asm__ ("movl $783, %%eax" : "=a" (result));//move eax to result variable

printf("Result: %d", result);

return 0;
}

This could help! using intel syntax in GCC:
