[9fans] plan9port and procexecl

[Dmitry Golubovsky]

Hi,

I have a piece of code which compiles and works fine in Plan9:

================================================

void
execproc(void *v)
{
        Channel *sync;
        Exec *e;
        int q[2];
        char *cmd;

        threadsetname("execproc");
        e = v;
        q[0] = e->q[0];
        q[1] = e->q[1];
        cmd = e->cmd;
        sync = e->sync;
        rfork(RFFDG);
        free(e);
        if(q[0]){
                dup(q[1], 1);
                close(q[0]);
                close(q[1]);
        }
        procexecl(sync, "/bin/rc", "rc", "-c", cmd, 0);
        sysfatal("can't exec");
}

================================================

(partly stolen from abaco, it runs a command in a proc and pipes the
output).

In plan9port the compiler complains for undefined procexecl, and  the
linker fails.

What would be the closest analog of procexecl for plan9port?

Thanks.
