LONG SE_log_open_log (SE_CONNECTION connection, const SE_LOGINFO loginfo, LONG mode, SE_LOG *log);
| connection | The connection handle |

| mode | The mode to use when the file is opened |
| log | The file handle to use when referencing this log file |
SE_log_open_log opens an SE_LOGINFO data structure in the specified mode on the ArcSDE server. This call is required to get a valid log file handle for subsequent log file operations. This function can create or open a log file on a layer or a registered table. The obsolete function SE_log_open can create log file on layers only. The following log file modes are supported:
SE_INPUT_MODE—Opens a log file in read-only mode. The log file can be owned by any user.
SE_OUTPUT_MODE—Creates and opens a new log file if one does not exist; otherwise, opens the existing log file. Any entries in an existing log file are deleted. The log file must be owned by the current user.
SE_EXTEND_MODE—Opens an existing log file and appends to it. The log file must exist and be owned by the current user.
SE_OUTPUT_NO_DELETE_MODE—Creates and opens a new log file. If the log file already exists, returns an SE_LOG_IO_ERROR error.

∙ Due to operating system limitations, it may be possible for two ArcSDE sessions of the same user name to simultaneously open the same log file. Therefore, it is possible that the edits of one session may overwrite those of another. You can avoid this by using SE_log_make_name.
