# NAG Library Function Document

## 1Purpose

nag_glopt_bnd_mcs_option_check (e05jhc) is used to check if you have set an optional parameter of nag_glopt_bnd_mcs_solve (e05jbc). The initialization function nag_glopt_bnd_mcs_init (e05jac) must have been called before calling nag_glopt_bnd_mcs_option_check (e05jhc).

## 2Specification

 #include #include
 Integer nag_glopt_bnd_mcs_option_check (const char *optstr, Nag_E05State *state, NagError *fail)

## 3Description

nag_glopt_bnd_mcs_option_check (e05jhc) returns 1 if you have previously set the optional parameter contained in optstr, otherwise it returns 0.
A complete list of optional parameters, their symbolic names and default values is given in Section 12 in nag_glopt_bnd_mcs_solve (e05jbc).

None.

## 5Arguments

1:    $\mathbf{optstr}$const char *Input
On entry: a string identifying an optional parameter (as described in Section 12 in nag_glopt_bnd_mcs_solve (e05jbc)).
2:    $\mathbf{state}$Nag_E05State *Communication Structure
state contains information required by other functions in this suite. You must not modify it directly in any way.
3:    $\mathbf{fail}$NagError *Input/Output
The NAG error argument (see Section 3.7 in How to Use the NAG Library and its Documentation).
