Returns a pointer to the SpmiCx structure corresponding to a specified context handle.
SPMI Library (libSpmi.a)
#include sys/Spmidef.h
struct SpmiCx *SpmiGetCx(CxHandle) SpmiCxHdl CxHandle;
The SpmiGetCx subroutine returns a pointer to the SpmiCx structure corresponding to the context handle identified by the CxHandle parameter.
Specifies a valid SpmiCxHdl handle as obtained by another subroutine call.
The SpmiGetCx subroutine returns a a pointer to an SpmiCx data structure if successful. If unsuccessful, the subroutine returns NULL.
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.
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.
