fmodsw - STREAMS module declaration structure

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

illumos DDI specific (illumos DDI)

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.

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

STREAMS Programming Guide

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