STREAMS Module Configuration

The following example shows the structures you need if you are working with a module instead of a driver. Notice that a modlstrmod(9S) is used in modlinkage(9S), and fmodsw(9S) points to streamtab(9S) instead of going through dev_ops(9S).

Example 11-2 Module Structures

extern struct streamtab pteminfo;

static struct fmodsw fsw = {
        "ptem",
        &pteminfo,
        D_NEW | D_MP
};

/*
 * Module linkage information for the kernel.
 */
extern struct mod_ops mod_strmodops;

static struct modlstrmod modlstrmod = {
        &mod_strmodops,
        "pty hardware emulator",
        &fsw
};

static struct modlinkage modlinkage = {
        MODREV_1, 
        (void *)&modlstrmod,
        NULL
};
