Returns a handle to use when referencing a context.
SPMI Library (libSpmi.a)
#include sys/Spmidef.h
SpmiCxHdl SpmiPathGetCx(CxPath, Parent) char *CxPath; SpmiCxHdl Parent;
The SpmiPathGetCx subroutine searches the context hierarchy for a given path name of a context and returns a handle to use when subsequently referencing the context.
Specifies the path name of the context to find. If you specify the fully qualified path name in the CxPath parameter, you must set the Parent parameter to NULL. If the path name is not qualified or is only partly qualified (that is, if it does not include the names of all contexts higher in the data hierarchy), the SpmiPathGetCx subroutine begins searching the hierarchy at the context identified by the Parent parameter. If the CxPath parameter is either NULL or an empty string, the subroutine returns a handle identifying the Top context.
Specifies the anchor context that fully qualifies the CxPath parameter. If you specify a fully qualified path name in the CxPath parameter, you must set the Parent parameter to NULL.
The SpmiPathGetCx subroutine returns a handle to a context if successful. If unsuccessful, the subroutine returns a NULL value.
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.
