Lhs — A C gateway function which provides the number of output arguments present in the calling Scilab function
nb_params Lhs
Lhs provides a C gateway function which provides the number of output arguments present in the calling Scilab function. You must include stack-c.h to benefit from this function.
Note: Lhs means Left Hand Side.
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).
In this example, the C gateway function can take several output arguments and prints in the Scilab console the integer corresponding to the number of output arguments detected in the calling Scilab function.
#include <stack-c.h>
#include <sciprint.h>
int sci_mylhs(char * fname)
{
sciprint("The number of output arguments is %d\n", Lhs);
return 0;
}
