e05jkc is used to get the value of an integer e05jbc optional parameter. e05jkc can be used before or after calling e05jbc, but the initialization function e05jac must have been called before calling e05jkc.

2 Specification

#include <nag.h>

void	e05jkc (const char optstr, Integer ivalue, Nag_E05State state, NagError fail)

The function may be called by the names: e05jkc or nag_glopt_bnd_mcs_optget_int.

3 Description

e05jkc obtains the current value of an integer-valued optional parameter. For example

e05jkc ('Local Searches Limit', &loclim, &state, &fail);

will result in the value of the optional parameter

Local Searches Limit

being output in loclim.

The default values of the optional parameters

Function Evaluations Limit

Splits Limit

and

Static Limit

depend on the problem parameter

n_{r}

(the number of non-fixed variables). A default value for each of these optional parameters will be set in the first call to the solver e05jbc: before that time, getting the value of any of these optional parameters using e05jkc will not return a meaningful result.

A complete list of optional parameters, their symbolic names and default values is given in Section 12 in e05jbc.

5 Arguments

1: $optstr$ – const char * Input: On entry: a string identifying an integer-valued optional parameter (as described in Section 12 in e05jbc).
2: $ivalue$ – Integer * Output: On exit: if $fail . code =$ NE_NOERROR on exit, ivalue contains the integer value associated with the optional parameter in optstr.
3: $state$ – Nag_E05State * Communication Structure: state contains information required by other functions in this suite. You must not modify it directly in any way.
4: $fail$ – NagError * Input/Output: The NAG error argument (see Section 7 in the Introduction to the NAG Library CL Interface).

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_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 8 in the Introduction to the NAG Library CL Interface for further information.
NE_NOT_INIT: Initialization function e05jac has not been called.
NE_OPT_NOT_READ: The supplied optional parameter is invalid. A keyword or keyword combination was not recognized.
