This boolean variable controls the automatic appending of the process ID number to the log file name. Set the value to 1 to enable appending, or 0 to disable. By default, appending is off.
With IRISODBCPID enabled, if the base log file is IRISODBC.log and is in your current directory, then the process ID of 21933 generates a full log file name of IRISODBC.log.21933.
Both IRISODBCPID and IRISODBCTRACEFILE affect the file name. For example, on Windows if you use IRISODBCTRACEFILE to set the base file name of the log file (for instance, to C:/home/mylogs/mylog.txt and enable IRISODBCPID, then log file names will be of the form C:/home/mylogs/mylog.txt.21965.
