Returns a data value for a given SpmiStatVals pointer by extraction from the data_feed packet. This subroutine call should only be issued from a callback function after it has been verified that a data_feed packet was received from the host identified by the first argument.
RSI Library (libSpmi.a)
#include sys/Rsi.h
float RSiGetValue(rhandle, svp)
RSiHandle rhandle;
struct SpmiStatVals *svp;
The RSiGetValue subroutine provides the following:
This subroutine is part of the Performance Toolbox for AIX® licensed product.
If successful, the subroutine returns a non-negative value; otherwise it returns a negative value less than or equal to -1.0. A NULL error text is placed in the external character array RSiEMsg regardless of the subroutine's success or failure.
All Remote Statistic Interface (RSI) 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 RSiErrno variable is set to RSiOkay and the RSiEMsg character array is empty. If an error is detected, the RSiErrno variable returns an error code, as defined in the enum RSiErrorType.
