CheckRhs (deprecated) C macro which checks the number of input arguments present in the calling Scilab function. This function is obsolete.

## Syntax

    CheckRhs(nb_min_params,nb_max_params)

## Arguments

nb_min_params

  The minimum number of input arguments which must be present in the calling Scilab function

nb_max_params

  the maximum number of input arguments which must be present in the calling Scilab function

## Description

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

If the number of input arguments is not between nb_min_params and nb_max_params, we quit the C interface (`return 0;`) and an error is returned in the Scilab console.

Since `CheckRhs` is doing a `return 0;` within the gateway function, it is important to call this macro before any memory allocation in order to avoid any memory leak.

WARNING: This API is deprecated from Scilab 5.2.0 and is going to be removed with Scilab 6.0. Please use API Scilab (the new Scilab API). This function has been replaced by CheckInputArgument.

## Examples

    #include "api_scilab.h"

    int sci_my_function(char *fname, unsigned long l)
    {
    /* The expected profile of the function will be:
    * a = my_function(a,b,c);
    */
      CheckRhs(3,3);
      CheckLhs(0,1);

    }
