modlstrmod(9S) Data Structures for Drivers modlstrmod(9S)NAME
modlstrmod - linkage structure for loadable STREAMS modules
SYNOPSIS
#include <sys/modctl.h>
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
DESCRIPTION
The modlstrmod structure is used by STREAMS modules to export module specific information to the kernel.
STRUCTURE MEMBERS
struct mod_ops *strmod_modops;
char *strmod_linkinfo;
struct fmodsw *strmod_fmodsw;
strmod_modops Must always be initialized to the address of mod_strmodops. This identifies the module as a loadable STREAMS mod-
ule.
strmod_linkinfo Can be any string up to MODMAXNAMELEN, and is used to describe the module. This string is usually the name of the
module, but can contain other information (such as a version number).
strmod_fmodsw Is a pointer to a template of a class entry within the module that is copied to the kernel's class table when the
module is loaded.

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 */

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

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
