SpmiGetStat Subroutine
Purpose
Returns a pointer to the SpmiStat structure corresponding to a specified statistic handle.
Library
SPMI Library (libSpmi.a)
Syntax
#include sys/Spmidef.h
struct SpmiStat *SpmiGetStat(StatHandle)
SpmiStatHdl StatHandle;
Description
The SpmiGetStat subroutine returns a pointer to the SpmiStat structure corresponding to the statistic handle identified by the StatHandle parameter.
This subroutine is part of the server option of the Performance Aide for AIX® licensed product.
Parameters
- StatHandle
-
Specifies a valid SpmiStatHdl handle as obtained by another subroutine call.
Return Values
The SpmiGetStat subroutine returns a pointer to a structure of type SpmiStat if successful. If unsuccessful, the subroutine returns a NULL 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.
