PROCESS PROPERTIES

version 11.3 (Modified)

PROCESS PROPERTIES (process; procName; procState; procTime{; procVisible{; uniqueID{; origin}}})

The PROCESS PROPERTIES command returns information about the process whose process number you pass in process.

After the call:

• procName returns the name of the process. Some things to note about the process name:

- If the process was started from the Execute Method dialog box (with the New Process option selected), its name is "P_" followed by a number.

- If the process was started from a custom menu item whose Start a New Process property is checked, the name of the process is "M_" or "ML_" followed by a number.

- If the process has been aborted (and its "slot" not reused yet), the name of the process is still returned. To detect if a process is aborted, test procState=-1 (see below).

• procState returns the state of the process at the moment of the call. This parameter can return one of the values provided by the following predefined constants:

• procTime returns the cumulative time that the process has used since it started, in ticks (1/60th of a second) .

• procVisible, if specified, returns TRUE if the process is visible, FALSE if hidden.

• uniqueID, if specified, returns the unique process number. Actually, each process has attributed a process number to it as well as a unique process number per session. The unique number allows you to differentiate between two processes or two process sessions. It corresponds to the process number having been started during 4D's session.

• origin, if specified, returns a value that describes the origin of the process. 4D offers the following predefined constants (in the "Process Type" theme):

Note: 4D's internal processes return a negative value and the processes generated by the user return a positive value.

If the process does not exist, which means you did not pass a number in the range 1 to Count tasks, PROCESS PROPERTIES leaves the variable parameters unchanged.

1. The following example returns the name, state, and time taken in the variables vName, vState, and vTimeSpent for the current process:

   C_STRING(80; vName) ` Initialize the variables
   C_INTEGER(vState)
   C_INTEGER(vTime)
   PROCESS PROPERTIES (Current process; vName; vState; vTimeSpent)

2. See example for On Exit Database Method.
