Getting Your Creator’s

Process Identifier

Your existing application might get the process ID of its creator directly using either

of:

The MOM procedure

The LOOKUPPROCESSNAME procedure

In either case, you must convert your program to use the corresponding D-series

procedure call as described in the following paragraphs.

Converting MOM Procedure Calls

Your existing application might get the process ID of its creator using the MOM

procedure as follows:

INT moms^process^id[0:3];

CALL MOM(moms^process^id);

Convert your program to use the D-series PROCESS_GETINFO_ procedure to return

the process handle instead:

INT my^process^handle[0:ZSYS^VAL^PHANDLE^WLEN - 1];

INT moms^process^handle[0:ZSYS^VAL^PHANDLE^WLEN - 1];

my^process^handle ':=' ZSYS^VAL^PHANDLE^WLEN * [-1];

CALL PROCESS_GETINFO_(my^process^handle,

!process^descriptor!,

!process^descriptor^length!,

!priority!,

moms^process^handle);

Converting LOOKUPPROCESSNAME Procedure Calls

Your existing application might get the process ID of its creator using the

LOOKUPPROCESSNAME procedure as follows:

INT ppd[0:9];

INT momsid[0:3];

ppd ':=' "$MYMOM ";

CALL LOOKUPPROCESSNAME(ppd);

momsid ':=' ppd[5] FOR 4;
