SpmiInstantiate Subroutine

Purpose

Explicitly instantiates the subcontexts of an instantiable context.

Library

SPMI Library (libSpmi.a)

Syntax

#include sys/Spmidef.h

int SpmiInstantiate(CxHandle)
SpmiCxHdl CxHandle;

Description

The SpmiInstantiate subroutine explicitly instantiates the subcontexts of an instantiable context. If the context is not instantiable, do not call the SpmiInstantiate subroutine.

An instantiation is done implicitly by the SpmiPathGetCx and SpmiFirstCx subroutine calls. Therefore, application programs usually do not need to instantiate explicitly.

This subroutine is part of the server option of the Performance Aide for AIX® licensed product.

Parameters

CxHandle

Specifies a valid context handle SpmiCxHdl as obtained by another subroutine call.

Return Values

The SpmiInstantiate subroutine returns a value of 0 if successful. If the context is not instantiable, the subroutine returns a nonzero value.

Error Codes

All SPMI subroutines use external variables to provide error information. To access these variables, an application program must define the following external variables:

• extern char SpmiErrmsg[];
• extern int SpmiErrno;

If the subroutine returns without an error, the SpmiErrno variable is set to 0 and the SpmiErrmsg character array is empty. If an error is detected, the SpmiErrno variable returns an error code, as defined in the sys/Spmidef.h file, and the SpmiErrmsg variable contains text, in English, explaining the cause of the error.
