CPXXcheckcopyctype and CPXcheckcopyctype

Checks the data about the type of variables copied in a model.

Signature


CPXCHECKLIBAPI
int CPXPUBLIC CPXXcheckcopyctype (CPXCENVptr env, 
                                  CPXCLPptr lp, 
                            const char *xctype);


CPXCHECKLIBAPI
int CPXPUBLIC CPXcheckcopyctype (CPXCENVptr env, 
                                 CPXCLPptr lp, 
                           const char *xctype);

Description

This routine validates the arguments of the corresponding routine CPXXcopyctype and CPXcopyctype. Specifically, when CPXXcopyctype and CPXcopyctype copies information about variable types in a given model, this routine checks that copied data. The source code of this data checking routine is in the file check.c, provided as part of the product.

To call this routine, you must compile and link check.c with your program as you compile and link with the CPLEX Callable Library.

Arguments

The arguments of this routine are the same as those of CPXXcopyctype and CPXcopyctype. The second argument, lp, is technically a pointer to a constant LP object of type CPXCLPptr rather than type CPXLPptr, because this routine does not modify the problem. For most user applications, this distinction is unimportant.

Name	Description
env	A pointer to the CPLEX environment as returned by `CPXXopenCPLEX/CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXXcreateprob/CPXcreateprob`.
xctype	An array of length `CPXgetnumcols(env,lp)` containing the type of each column in the constraint matrix. Possible values appear in Table 1.

Return

The routine returns nonzero if it detects an error in the data; it returns zero if it does not detect any data errors.

Example


 status = CPXXcheckcopyctype (env, lp, ctype);
