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
Solaris DDI specific (Solaris 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 WARN-
INGS.)
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 */
SEE ALSO mt-streams(9F), modlstrmod(9S), module_info(9S)
STREAMS Programming Guide
WARNINGS
If f_name does not match the module binary name, unexpected failures can occur.

Intro(9S) Data Structures for Drivers Intro(9S)NAME
Intro, intro - introduction to kernel data structures and properties
DESCRIPTION
Section 9P describes kernel properties used by device drivers. Section 9S describes the data structures used by drivers to share informa-
tion between the driver and the kernel. See Intro(9E) for an overview of device driver interfaces.
In Section 9S, reference pages contain the following headings:
o NAME summarizes the purpose of the structure or property.
o SYNOPSIS lists the include file that defines the structure or property.
o INTERFACE LEVEL describes any architecture dependencies.
o DESCRIPTION provides general information about the structure or property.
o STRUCTURE MEMBERS lists all accessible structure members (for Section 9S).
o SEE ALSO gives sources for further information.
Of the preceding headings, Section 9P reference pages contain the NAME, DESCRIPTION, and SEE ALSO fields.
Every driver MUST include <sys/ddi.h> and <sys/sunddi.h>, in that order, and as final entries.
The following table summarizes the STREAMS structures described in Section 9S.

Do not declare arrays of structures as the size of the structures can change between releases. Rely only on the structure members listed in
this chapter and not on unlisted members or the position of a member in a structure.
