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


If f_name does not match the module binary name, unexpected failures can
occur.
