Re: Re: Change processname for dmix/dsnoop process

Actually, I found it - it's SYS_prctl with PR_SET_NAME (2.6 kernels only).

Something like this:

static inline int prctl(int option, unsigned long arg2, unsigned long arg3,
                        unsigned long arg4, unsigned long arg5)
{
    int ret;
    __asm__ __volatile__ ( "pushl %%ebx; movl %2,%%ebx; int $0x80; popl %%ebx"
                           : "=a" (ret) : "0" (SYS_prctl), "r" (option),
                           "c" (arg2), "d" (arg3), "S" (arg4), "D" (arg5) );
    return SYSCALL_RET(ret);
}

prctl(15 /* PR_SET_NAME */, (unsigned long)"dmix", 0, 0, 0);

thanks -mike
