gn_closecnt Subroutine

Purpose

Maintains the using count on a gnode structure.

Syntax

#include <sys/vnode.h>
#include <sys/fcntl.h>

void gn_closecnt (gnode, flags) struct gnode *gnode; long flags;

Parameters

Item	Description
gnode	Points to a gnode structure.
flags	Specifies the open mode (FREAD, FWRITE, FEXEC, FRSHARE) from the open file flags.

Description

The gn_closecnt subroutine uses the passed in flags value to determine the appropriate using counts to decrease in the gnode structure. For example, if the FREAD flag is set, the gn_closecnt subroutine decreases the gn_rdcnt field. The following table shows the mapping of the flags value to the counts field in the gnode structure:

Item	Description
FREAD	gn_rdcnt
FWRITE	gn_wrcnt
FEXEC	gn_excnt
FRSHARE	gn_rshcnt

Return Values

The gn_closecnt subroutine returns no return values.

Error Codes

The gn_closecnt subroutine returns no error codes.
