NAME

module_info– STREAMS driver identification and limit value structure

SYNOPSIS

#include <sys/stream.h> 

INTERFACE LEVEL

Architecture independent level 1 (DDI/DKI).

DESCRIPTION

When a module or driver is declared, several identification and limit values can be set. These values are stored in the module_info structure.

The module_info structure is intended to be read-only. However, the flow control limits ( mi_hiwat and mi_lowat) and the packet size limits ( mi_minpsz and mi_maxpsz) are copied to the QUEUE structure, where they may be modified.

STRUCTURE MEMBERS

ushort_t      mi_idnum;      /* module ID number */
char          *mi_idname;    /* module name */
ssize_t       mi_minpsz;     /* maximum packet size */
size_t        mi_hiwat;      /* high water mark */
size_t        mi_lowat;      /* low water mark */

The constant FMNAMESZ, limiting the length of a module's name, is set to eight in this release.
