e04rzc is a part of the NAG optimization modelling suite. It is used to deallocate the memory used within the problem handle and to destroy the handle itself.

2 Specification

#include <nag.h>

void	e04rzc (void *handle, NagError fail)

The function may be called by the names: e04rzc or nag_opt_handle_free.

3 Description

Each problem handle initialized by e04rac should be deallocated to avoid memory leaks. Therefore e04rzc should be called on all the handles which are no longer needed, typically after obtaining results from the solver. Please note that passing a handle which has not been initialized by e04rac might cause unpredictable behaviour, including a crash of your program. See Section 4.1 in the E04 Chapter Introduction for more details about the NAG optimization modelling suite.

4 References

None.

5 Arguments

1: $handle$ – void ** Input/Output: On entry: the handle to the problem. It needs to be initialized by e04rac and must not be changed before the call to e04rzc.

On exit: the handle is destroyed and set to NULL.
2: $fail$ – NagError * Input/Output: The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).

6 Error Indicators and Warnings

NE_ALLOC_FAIL: Dynamic memory allocation failed.
See Section 3.1.2 in the Introduction to the NAG Library CL Interface for further information.
NE_BAD_PARAM: On entry, argument $〈value〉$ had an illegal value.
NE_HANDLE: The supplied handle does not define a valid handle to the data structure for the NAG optimization modelling suite. It has not been initialized by e04rac or it has been corrupted.
NE_INTERNAL_ERROR: An internal error has occurred in this function. Check the function call and any array sizes. If the call is correct then please contact NAG for assistance.
See Section 7.5 in the Introduction to the NAG Library CL Interface for further information.
NE_NO_LICENCE: Your licence key may have expired or may not have been installed correctly.
See Section 8 in the Introduction to the NAG Library CL Interface for further information.

7 Accuracy

Not applicable.

8 Parallelism and Performance

e04rzc is not threaded in any implementation.

9 Further Comments
