    Format

      F$GETJPI(pid,item)

1  –  Return Value

    Either an integer or a character string, depending on the item
    you request.

2  –  Arguments

 pid

    Specifies the process identification (PID) number of the process
    for which information is being reported. Specify the pid argument
    as a character string expression. You can omit the leading zeros.

    If you specify a null string (""),  the current PID number is
    used.

    You cannot use an asterisk (*)  or percent sign (%) wildcard
    character to specify the pid argument in the F$GETJPI function,
    as you can with the $GETJPI system service. To get a list of
    process identification numbers, use the F$PID function.

 item

    Indicates the type of process information to be returned. Specify
    the item argument as a character string expression. You can
    specify any one of the following items:

3  –  Examples

    1.$ NAME = F$GETJPI("3B0018","USERNAME")
      $ SHOW SYMBOL NAME
        NAME = "JANE        "

      This example shows how to use the F$GETJPI function to return
      the user name for the process number 3B0018. The user name is
      assigned to the symbol NAME.

    2.$ X=F$ENVIRONMENT("MESSAGE")
      $ SHOW SYMBOL X
        X = "/FACILITY/SEVERITY/IDENTIFICATION/TEXT"
      $ X=F$GETJPI("0","MSGMASK")
      $ SHOW SYMBOL X
        X = 15   Hex = 0000000F  Octal = 00000000017
      $ SET MESSAGE /NOFACILITY
      $ X=F$ENVIRONMENT("MESSAGE")
      $ SHOW SYMBOL X
        X = "/NOFACILITY/SEVERITY/IDENTIFICATION/TEXT"
      $ X=F$GETJPI("0","MSGMASK")
      $ SHOW SYMBOL X
        X = 7   Hex = 00000007  Octal = 00000000007
      $ SET MESSAGE /FACILITY
      $ X=F$ENVIRONMENT("MESSAGE")
      $ SHOW SYMBOL X
        X = "/FACILITY/SEVERITY/IDENTIFICATION/TEXT"
      $ X=F$GETJPI("0","MSGMASK")
      $ SHOW SYMBOL X
        X = 15   Hex = 0000000F  Octal = 00000000017
      $

      This example shows the use of the F$GETJPI MSGMASK item.
