CPXchgcolname

int CPXPUBLIC CPXchgcolname(CPXCENVptr env, CPXLPptr lp, int cnt, const int * indices, char ** newname)

Definition file: cplex.h

Include files: cplex.h

The routine CPXchgcolname changes the names of variables in a CPLEX problem object. If this routine is performed on a problem object with no variable names, default names are created before the change is made.

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXcreateprob`.
cnt	An integer that indicates the total number of variable names to be changed. Thus `cnt` specifies the length of the arrays `indices` and `newname`.
indices	An array of length `cnt` containing the numeric indices of the variables for which the names are to be changed.
newname	An array of length `cnt` containing the strings of the new variable names for the columns specified in `indices`.

Returns:

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