CPXXgetqconstrindex and CPXgetqconstrindex
The routine CPXXgetqconstrindex/CPXgetqconstrindex searches for the index number
of the specified quadratic constraint in a CPLEX problem object.
int CPXXgetqconstrindex( CPXCENVptr env, CPXCLPptr lp, char const * lname_str, CPXDIM * index_p )
int CPXgetqconstrindex( CPXCENVptr env, CPXCLPptr lp, char const * lname_str, int * index_p )
Description
The routine CPXXgetqconstrindex/CPXgetqconstrindex searches for the index number
of the specified quadratic constraint in a CPLEX problem object.
Arguments
- 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. - lname_str
- A quadratic constraint name to search for.
- index_p
-
A pointer to an integer to hold the index number of the quadratic constraint with name
lname_str. If the routine is successful,*index_pcontains the index number; otherwise,*index_pis undefined.
Return
The routine returns 0 (zero) on success and nonzero if an error occurs.Example
status = CPXgetqconstrindex (env, lp, "resource89", &qconstrindex);
