# getNbInputArgument (Scilab gateway)

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

## Calling Sequence

    nb_params = getNbInputArgument(void* _pvCtx)

    nb_params = nbInputArgument

    nb_params = Rhs

## Arguments

_pvCtx

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

nb_params

  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;
    }
