I want to kiss you all over, that worked.

Here's the working function:

Code: Select all

void getCPUVendor(char *rtn)
{
      asm volatile(
      ".intel_syntax noprefix;"
      "mov eax,0;"
      "cpuid;"
      "mov [%0],ebx;" 
      "mov [%0+4],edx;"
      "mov [%0+8],ecx;"
      "movb [%0+12],0;"
      ".att_syntax;" : : "r" (rtn) : "eax", "ebx", "ecx", "edx"
      );
}
