1 Purpose

e05jec may be used to supply individual ‘ON’/‘OFF’-valued character optional parameters to e05jbc. The initialization function e05jac must have been called before calling e05jec.

2 Specification

#include <nag.h>
void  e05jec (const char *optstr, const char *cvalue, Nag_E05State *state, NagError *fail)
The function may be called by the names: e05jec or nag_glopt_bnd_mcs_optset_char.

3 Description

e05jec may be used to supply values for ‘ON’/‘OFF’-valued character optional parameters to e05jbc. It is only necessary to call e05jec for those arguments whose values are to be different from their default values. One call to e05jec sets one argument value.
Each ‘ON’/‘OFF’-valued character optional parameter is defined by a single character string in optstr and the corresponding value in cvalue. For example, the following allows local searches to be turned off:
strcpy(&lcsrch[0],"Off");
e05jec ('Local Searches', lcsrch, &state, &fail);
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 defining a single ‘ON’/‘OFF’-valued character optional parameter (as described in Section 12 in e05jbc).
2: cvalue const char * Input
On entry: the ‘ON’/‘OFF’ value associated with the keyword 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).

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_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.
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.
NE_OUT_OF_RANGE
Attempt to assign an illegal value of Local Searches (lcsrch): lcsrch=value.
Attempt to assign an illegal value of Repeatability (repeat): repeat=value.

7 Accuracy

Not applicable.

8 Parallelism and Performance

Background information to multithreading can be found in the Multithreading documentation.
e05jec is threaded by NAG for parallel execution in multithreaded implementations of the NAG Library.
Please consult the X06 Chapter Introduction for information on how to control and interrogate the OpenMP environment used within this function. Please also consult the Users' Note for your implementation for any additional implementation-specific information.

9 Further Comments

e05jcc or e05jdc may also be used to supply ‘ON’/‘OFF’-valued character optional parameters to e05jbc.
