CPXNETgetarcindex

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

Definition file: cplex.h

Include files: cplex.h

The routine CPXNETgetarcindex returns the index of the specified arc (in the network stored in a network problem object) in the integer pointed to by index_p.

Example

 status = CPXNETgetarcindex (env, net, "from_a_to_b", &index);

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
net	A pointer to a CPLEX network problem object as returned by `CPXNETcreateprob`.
lname_str	Name of the arc to look for.
index_p	A pointer to an integer to hold the arc index. If the routine is successful, `index_p` contains the index number; otherwise, `index_p` is undefined.

Returns:

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