The following example formats an Error Log record for display. The calling program has placed the address of the locale object in locale.

   #define INCL_LOGGING
   #include <unichar.h>
   #include <os2.h>
   #include <stdio.h>
           .
{
   APIRET rc;                              /* return code */
   ULONG service;
   LFEREQUEST format_entry_packet;
   BYTE log_entry_buffer[1024];
   UniChar string_buffer[2048];
   #define STRING_BUFFER_LENGTH 2048
   ULONG string_buffer_length;
   PVOID locale;

   service = ERROR_LOGGING_SERVICE;
   string_buffer_length = STRING_BUFFER_LENGTH;

   /*   Construct the Error Log Service format packet  */
   format_entry.packet.packet_size = sizeof(LFEREQUEST);
   format_entry_packet.packet_revision_number = WPOS_RELEASE_1;
   format_entry_packet.log_entry_buffer =  &log_entry_buffer;
   format_entry_packet.flags = ERR_FORMAT_DETAIL_DATA;
   format_entry_packet.locale_object = locale;
   format_entry_packet.string_buffer_length = &string_buffer_length;
   format_entry_packet.string_buffer =  &string_buffer;
   rc = LogFormatEntry(service,            /* service */
                   &format_entry_packet)   /* parameter packet */
   if (rc != 0)
           {
           printf("LogFormatEntry error: return code = %d",rc);
           return;
           }
