getNbInputArgument (Scilab gateway)

A C gateway function which provides the number of input arguments present in the calling Scilab function

Syntax

int* nb_params = getNbInputArgument(void* _pvCtx)
int nb_params = nbInputArgument(void* _pvCtx)
int nb_params = Rhs

Arguments

_pvCtx

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

nb_params

the pointer on the number of input arguments present in the calling Scilab function

Description

A C gateway function which provides the number of input arguments present in the calling Scilab function. You must include api_scilab.h to benefit from this function.

Examples

In this example, the C interface function can take several input arguments and prints in the Scilab console the integer corresponding to the number of input arguments detected in the calling Scilab function.

#include "api_scilab.h"
#include "sciprint.h"

int sci_myrhs(char * fname)
{
  sciprint("The number of input parameters is %d\n", *getNbInputArgument());

  return 0;
}
