ARGCOUNT

Purpose:

Returns the number of arguments specified in an SPL function.

ARGCOUNT

A real.

myfun(a, b, c, d)
{
return(argcount);
}

myfun(1) returns: 1

myfun(1, 1, 10) returns: 3

myfun2(a, b)
{
    if (argc < 2)
    {
        if (argc < 1) a = 10;

        b = 100;
    }

    return(a * b);
}

myfun2() returns: 1000

myfun2(1) returns: 100

Arguments to SPL functions are optional. ARGCOUNT is a simple method for checking if an argument was specified.

ARGCOUNT can be abbreviated ARGC.

ARGC returns the total number of input arguments. See ARGV to specify variables arguments in an SPL routine.

See OUTARGC for a count of output arguments.

See Optional Function Arguments for more information on optional SPL arguments.
