CheckLhs (deprecated)

C macro which checks the number of output arguments present in the calling Scilab function. This function is obsolete.

Calling Sequence

CheckLhs(nb_min_params,nb_max_params)

Arguments

nb_min_params

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

nb_max_params

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

Description

C macro which checks the number of output arguments present in the calling Scilab function. You must include stack-c.h to benefit from this function.

If the number of 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 CheckLhs 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 This function has been replaced by CheckOutputArgument.

Examples

#include "stack-c.h"

#error This code is deprecated

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(1,1);

}
