FMODSW(9S) Data Structures for Drivers FMODSW(9S)

NAME

fmodsw - STREAMS module declaration structure

SYNOPSIS

#include <sys/stream.h>
#include <sys/conf.h>

INTERFACE LEVEL

illumos DDI specific (illumos DDI)

DESCRIPTION

The fmodsw structure contains information for STREAMS modules. All
STREAMS modules must define a fmodsw structure.


f_name must match mi_idname in the module_info structure. See
module_info(9S). f_name should also match the module binary name.
(See WARNINGS.)


All modules must set the f_flag to D_MP to indicate that they safely
allow multiple threads of execution. See mt-streams(9F) for
additional flags.

STRUCTURE MEMBERS

char f_name[FMNAMESZ + 1]; /* module name */
struct streamtab *f_str; /* streams information */
int f_flag; /* flags */

WARNINGS

can occur.
