gfdOpenStatusFile( )

Description | Example

Name:	int gfdOpenStatusFile (int chassis, int mode)
Inputs:	int chassis	The chassis number.
	int mode	The access mode of the file, which is defined in the include file fcntl.h. The mode passed must be O_RDONLY.
Outputs:	none
Returns:	Handle to the open status file	Successful.
	-1	An error occurred.
Includes:	gfdstatu.h

Description

The gfdOpenStatusFile( ) function creates the name of the status file and attempts to open it. The path for the status file is obtained from the GFAX environment variable. Low-level functions, such as gfdReadStatusFileHeader and gfdReadStatusFileRecord, cannot be used unless gfdOpenStatusFile is called first successfully.

Example

#include "gfdstatu.h"  
int chassis = 1; /* Default to one chassis*/  
int status_fid;  
status_fid = gfdOpenStatusFile(chassis, O_RDONLY);  
if (status_fid < 0)  
{  
   printf ("No status file open.\n");  
   exit (1);  
}
