of nodes in a network stored in a network problem object.
CPXDIM CPXXNETgetnumnodes( CPXCENVptr env, CPXCNETptr net )
int CPXNETgetnumnodes( CPXCENVptr env, CPXCNETptr net )
Description

of nodes in a network stored in a network problem object.
Arguments
- env
-
A pointer to the CPLEX environment as returned by
CPXXopenCPLEX/CPXopenCPLEX. - net
-
A pointer to a CPLEX network problem object as returned by
CPXXNETcreateprob/CPXNETcreateprob.
Return
The routine returns the number of network nodes stored in a network problem object. If an error occurs, 0 is returned and an error message is issued.Example
