Returns information on the current process.
1 – Input
An integer value specifying the item of information that the
FN$PROCESS_INFO function is to return; the integer value is one
of the values used by the $GETJPI system service.
DEC DATATRIEVE supplies a table associating symbolic strings to
values of the $GETJPI system service. The table is called JPI_
CODES, located in CDD$TOP.DTR$LIB. If you use the JPI_CODES table
with this function, the syntax is:
FN$PROCESS_INFO ("symbolic-string" VIA CDD$TOP.DTR$LIB.JPI_CODES)
Where symbolic-string is a text string defined in JPI_CODES. The
text string must be placed inside quotation marks.
For a complete description of the item codes, see the $GETJPI
service documented in the OpenVMS System Services Reference
Manual.
2 – Output
A text string containing the information requested by the item-
code.
3 – Examples
The following examples shows how the FN$PROCESS_INFO function
returns information about the username; the first example uses an
