Boolean reading (Scilab gateway)

How to read matrix of boolean in a list.

Calling Sequence

Input argument profile:

SciErr getMatrixOfBooleanInList(void* _pvCtx, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int** _piBool)

Named variable profile:

SciErr readMatrixOfBooleanInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int* _piBool)

Arguments

_pvCtx

Scilab environment pointer, pass in "pvApiCtx" provided by api_scilab.h.

_piParent

Address of the parent of the new item.

_pstName

Name of the variable for "named" functions.

_iItemPos

Position of the new item in the list.

_piRows

Return number of rows of the variable.

_piCols

Return number of columns of the variable.

_piBool

Return address of data array (size: _iRows * _iCols).

SciErr

Error structure where is stored errors messages history and first error number.

Description

This help describes how to read matrix of boolean in a list.
