Command Definitions (HPMERGEEND-LOGSTATUS)
HPSWTONMPLABEL
HPSWTONMPLABEL
CM callable only.
Allows CM user programs, user libraries, and system code to invoke NM procedures as
follows:
• Convert CM references in the argument list to virtual NM addresses.
• Change the execution mode.
• Invoke the NM procedure specified by the CM caller.
Syntax
U32V I16V I16 I16
status:=HPSWTONMPLABEL(
proc,nparms,arglist,argdesc,
I16V
functype );
Functional Return
status I32 (assigned functional return)
Returns a 32-bit integer indicating the status of the call.
Parameters
proc 32-bit unsigned integer by value (required)
Passes the NM plabel of the target procedure name. This plabel is usually
obtained by calling the HPLOADNMPROC intrinsic.
nparms 16-bit signed integer by value (required)
Passes the number of parameters to be passed to the target NM procedure.
It specifies the length of
argdesc . Account for any hidden parameters
(such as, parameters, an extensible parameter list, and so forth). .
arglist 16-bit signed integer array by reference (required)
Passes the actual parameters to be passed to the NM procedure.
argdesc 16-bit signed integer array by reference (required)
Passes integer codes describing the parameters held in the
arglist array
(that is, byte, word, double, pointer, and so forth).
functype 16-bit signed integer by value (required)
Passes the data type of the value the target procedure returns if it is a
function. If the target is not a function, the value of this parameter is zero.
Refer to the Switch Programming Guide for supported function types.
