SpmiFreeHotSet Subroutine


Erases a hotset.


SPMI Library (libSpmi.a)


#include sys/Spmidef.h

int SpmiFreeHotSet(HotSet)
struct SpmiHotSet *HotSet;


The SpmiFreeHotSet subroutine erases the hotset identified by the HotSet parameter. All SpmiHotVals structures chained off the SpmiHotSet structure are deleted before the set itself is deleted.



Specifies a pointer to a valid structure of type SpmiHotSet as created by the SpmiCreateHotSet subroutine call.

Return Values

The SpmiFreeHotSet subroutine returns a value of 0 if successful. If unsuccessful, 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:

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. See the List of SPMI Error Codes for more information.

Implementation Specifics

This subroutine is part of the server option of the Performance Aide for AIX licensed product and is also included in the Performance Toolbox for AIX licensed product.


/usr/include/sys/Spmidef.h Declares the subroutines, data structures, handles, and macros that an application program can use to access the SPMI.
