CPXXNETgetnodeindex and CPXNETgetnodeindex

The routine CPXXNETgetnodeindex/CPXNETgetnodeindex returns the index of the specified node (in the network stored in a network problem object) in the integer pointed to by index_p.

int CPXXNETgetnodeindex( CPXCENVptr env, CPXCNETptr net, char const * lname_str, CPXDIM * index_p )

int CPXNETgetnodeindex( CPXCENVptr env, CPXCNETptr net, char const * lname_str, int * index_p )

Description

The routine CPXXNETgetnodeindex/CPXNETgetnodeindex returns the index of the specified node (in the network stored in a network problem object) in the integer pointed to by index_p.

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.
lname_str: Name of the node to look for.
index_p: A pointer to an integer to hold the node index. If the routine is successful, *index_p contains the index number; otherwise, *index_p is undefined.

Return

The routine returns 0 (zero) on success and nonzero if an error occurs.

Example


 status = CPXNETgetnodeindex (env, net, "root", &index);
