Function Documentation

long jit_atom_arg_getdouble	(	double *	c,
		long	idx,
		long	ac,
		t_atom *	av
	)

Retrieves atom argument at index as double precision floating point number if present.

This function is useful for setting the values only if there is an argument at the specified index, otherwise, the input value is untouched.

Parameters:

c	pointer to double (should contain desired default)
idx	atom argument index
ac	atom argument count
av	atom argument vector

Returns:

t_jit_err error code. JIT_ERR_NONE if successful.

long jit_atom_arg_getfloat	(	float *	c,
		long	idx,
		long	ac,
		t_atom *	av
	)

Retrieves atom argument at index as floating point number if present.

This function is useful for setting the values only if there is an argument at the specified index, otherwise, the input value is untouched.

Parameters:

c	pointer to float (should contain desired default)
idx	atom argument index
ac	atom argument count
av	atom argument vector

Returns:

t_jit_err error code. JIT_ERR_NONE if successful.

long jit_atom_arg_getlong	(	long *	c,
		long	idx,
		long	ac,
		t_atom *	av
	)

Retrieves atom argument at index as long integer if present.

This function is useful for setting the values only if there is an argument at the specified index, otherwise, the input value is untouched.

Parameters:

c	pointer to long (should contain desired default)
idx	atom argument index

long jit_atom_arg_getsym	(	t_symbol **	c,
		long	idx,
		long	ac,
		t_atom *	av
	)

Retrieves atom argument at index as symbol pointer if present.

This function is useful for setting the values only if there is an argument at the specified index, otherwise, the input value is untouched.

Parameters:

c	pointer to symbol pointer (should contain desired default)
idx	atom argument index
