LogFormatEntry

From EDM2

LogFormatEntry formats a Log Entry for display.

Syntax

LogFormatEntry(service, pFormatEntry)

Parameters

service (ULONG) - input
The class of Logging Service:
  • Error logging
  • All other values are reserved for future use.
pFormatEntry (PVOID) - input
A pointer to the LogFormatEntry parameter packet.
  • For Error Logging, this is a pointer to a LFEREQUEST structure.

Returns

rc (APIRET) - returns
Return code.
LogFormatEntry returns the following values:
  • No error
  • 2 Error file not found

Remarks

ADDITIONAL RETURNS INFORMATION

The data will be passed back in multiple occurrences of the following LTD (Length, Type, Data) format: 

ULONG
    length ULONG
    type UniChar
    data[n] or
Char
    data[n]

Where:

  • length (ULONG) is the length, in bytes, of this detail record (includes length, type, and data fields).
  • type (ULONG) is an integer value that represents the type of data being passed back.

An error record is created by the system when an error in a system or application program triggers a probe in that program. Error records contain detailed information to help you diagnose the error. Error records are also called DET1 records. Records created by a back level logging system are called DET4 records.

A control record is created by the system when you make changes to the way errors are logged. For example, when you suspend error logging or direct error logging to a new file, the system records that change in a control record. Control records are also called DET2 records. Control records are new for FFST technology and are not available in records created by a back level logging system.

The following are the current Error Logging type values and their meanings:

data (UniChar[]) or data (Char[]) is a variable length area that contains the formatted data.

Note: If there is no data, only the length and type portion of the record will be returned. The length would indicate that there is no data.

The library LFAPI.LIB must be linked with object files that use LogFormatEntry

The packet_revision_number parameter defines if pointers point to ASCII or UniCode character data.

Example Code

#define INCL_LOGGING
#include <os2.h>
#include <lfdef.h>

ULONG     service;
PVOID     pFormatEntry;
APIRET    rc;

rc = LogFormatEntry(service, pFormatEntry);

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 <unidef.h>
  #include <os2.h>
  #include <stdio.h>
  #include <lfdef.h>

  {
  APIRET rc;                              /* return code */
  ULONG service;
  LFEREQUEST format_entry_packet;
  BYTE log_entry_buffer[1024];
  UniChar string_buffer[4096];
  #define STRING_BUFFER_LENGTH 4096
  ULONG string_buffer_length;
  LocaleObject locale;

  service = ERROR_LOGGING_SERVICE;
  string_buffer_length = STRING_BUFFER_LENGTH;
  rc = UniCreateLocaleObject(UNLUCS_STRING_POINTNER,(UniChar *) L"",&locale);
  if (rc |= 0)
    {
     printf("UniCreateLocaleObject error: return code = %d",rc);
     return;
    }

  /* 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;
    }
