dce_cf_get_host_name(3dce)  —  Subroutines

Name

dce_cf_get_host_name - Returns the host name relative to the local cell root

Synopsis

#include <stdio.h>
#include <dce/dce_cf.h> void dce_cf_get_host_name(
char ∗∗hostname,
error_status_t ∗status);

Parameters

Input

None. 

Input/Output

hostnameThe address of a string pointer.  This pointer will be set by the function to point to a buffer that contains the host name. 

Output

statusReturns the status code from this operation.  The status code is a value that indicates whether the routine completed successfully and if not, why not. 

Description

The dce_cf_get_host_name() routine searches the DCE configuration file for the local host’s name relative to the local cell’s root.  If the name is found, dce_cf_get_host_name() allocates (by a call to malloc()) a buffer for it, copies the name into the buffer, and returns its address in the hostname input parameter. 

Cautions

The memory for a returned name string is allocated by malloc(), and must be freed by the caller of dce_cf_get_host_name(). 

Files

dcelocal/dce_cf.db
The machine’s local DCE configuration file (where dcelocal is usually something like /opt/dcelocal). 

Errors

The following describes a partial list of errors that might be returned.  Refer to the OSF DCE Problem Determination Guide for complete descriptions of all error messages. 

dce_cf_st_ok
Operation successfully completed.

dce_cf_e_file_open
File open error.

dce_cf_e_no_mem
No memory available.

dce_cf_e_no_match
No host name entry in the DCE configuration file.
