When your program creates a process, it can programmatically pass information
to the child process with:
The param parameter of the CREATE intrinsic
Item numbers 2 and/or 11 of the CREATEPROCESS intrinsic
The parm and/or info parameters of the :RUN command
The GETINFO intrinsic enables your program to retrieve this information.
This is an example of a GETINFO intrinsic call:
GETINFO (INFO,MAXLENGTH,PARAMETER);
|
The parameters specified in the example are described below.
- INFO
Returns the contents of the info parameter from the :RUN command or
Item Number 11 from CREATEPROCESS.
- MAXLENGTH
Passes the maximum number of characters that MPE/iX is allowed
to move to INFO. MAXLENGTH returns the number of characters actually moved to
INFO by MPE/iX. MPE/iX will not move a number of characters greater than the
original value of MAXLENGTH.
- PARAMETER
Returns the contents of the parm parameter from the :RUN
command, item number 2 from CREATEPROCESS, or the param parameter from CREATE.
