CPXNETwriteprob

The routine CPXNETwriteprob writes the network stored in a network problem object to a file. This can be done in CPLEX (.net) or DIMACS (.min) network file format (MIN) or as the LP representation of the network in any of the LP formats (.lp, .mps, or .sav).

If the file name ends with .gz, a compressed file is written.

File extensions for network files
net	for CPLEX network format
min	for DIMACS network format
lp	for LP format of LP formulation
mps	for MPS format of LP formulation
sav	for SAV format of LP formulation

Example

 status = CPXNETwriteprob (env, net, "network.net", NULL);

A pointer to the CPLEX environment as returned by CPXopenCPLEX.

A pointer to a CPLEX network problem object as returned by CPXNETcreateprob.

Name of the network file to write, where the file extension specifies the file format unless overridden by the format argument. If the file name ends with .gz a compressed file is written in accordance with the selected file type.

File format to generate. Possible values appear in the table. If NULL is passed, the format is inferred from the file name.

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

Parameters:

Returns:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
net	A pointer to a CPLEX network problem object as returned by `CPXNETcreateprob`.
filename_str	Name of the network file to write, where the file extension specifies the file format unless overridden by the `format` argument. If the file name ends with `.gz` a compressed file is written in accordance with the selected file type.
format_str	File format to generate. Possible values appear in the table. If NULL is passed, the format is inferred from the file name.
