user_io

int user_io(void *user)

Description:

Here, the user can read in an instance in a custom format and set up appropriate data structures. If the user wants to use the default parsers to read either an MPS file or a GMPL/AMPL file, then the return value USER_DEFAULT should be specified (see user_readparams for the command-line switches to use to specify this behavior).

Arguments:

void *user

IN

Pointer to the user-defined data structure.

Return values:

USER_ERROR	Error. SYMPHONY stops.
USER_SUCCESS	User I/O was completed successfully.
USER_DEFAULT	Input will be read in from an MPS or GMPL/AMPL file.
