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)
float RSiGetValue(rhandle, svp) RSiHandle rhandle; struct SpmiStatVals *svp;
The RSiGetValue subroutine provides the following:
rhandleMust be an RSiHandle, previously initialized by the RSiOpen (RSiOpen Subroutine) subroutine.
svpA handle of type struct SpmiStatVals, which was previously returned by a successful RSiPathAddSetStat (RSiPathAddSetStat Subroutine) subroutine call.
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 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. RSi error codes are described in List of RSi Error Codes.
This subroutine is part of the Performance Toolbox for AIX licensed product.
