Data Structure Documentation

struct t_edsp

The DSP structure.

It contains all the members for signal processing. This should be used for no graphical object that have signal processing methods.

Data Fields
float	d_float	The float member to initialize the signal method.
long	d_size	The number of signal inlets and outlets.
t_int *	d_vectors	The vector that contains all the pointers for the perform method.
long	d_flags	The flags to initialize the perform method.
void *	d_user_param	The user parameters to pass through the perform method.
t_float **	d_sigs_out	The array of signal vectors.
t_float *	d_sigs_real	The real array of signal.
t_typ_method	d_perform_method	The user perform method.
long	d_misc	The flag that could be inplace or not.

struct t_edspobj

The DSP object.

It contains the t_eobj with the t_edsp structure. This should be used for no graphical object that have signal processing methods.

Data Fields
t_eobj	d_obj	The default object.
t_edsp	d_dsp	The dsp structure.

struct t_edspbox

The GUI DSP object.

It contains the t_eobj with all the members for graphical behavior and signal processing. This should be used for graphical object that have signal processing methods.

t_symbol *	b_all_id	The global ID.
long	b_flags	The ebox flags.
t_rect	b_rect	The ebox rectangle.
t_rect	b_rect_last	The ebox previous rectangle.
t_efont	b_font	The ebox font.
int	b_selected_box	The selected state
int	b_selected_item	The items selected.
int	b_selected_inlet	The inlet selected.

long	b_number_of_layers	The ebox number of layers.
t_edsp	d_dsp	The dsp structure.

Enumeration Type Documentation

enum edsp_flags

The flags that discribe the behavior of a t_edspobj.

It define all the behavior of a t_edspobj.

Enumerator
E_INPLACE	The signal processing can be inplace.
E_NO_INPLACE	The signal processing can't be inplace.

Function Documentation

void eobj_dspsetup	(	void *	x,
		long	nins,
		long	nouts
	)

Initializes the dsp members of the t_edsp.

Allocate the memory for digital dignal processing of a t_edspobj.
This funtion should replace inlet_new and outlet_new for the signal.

Parameters

x	The edspobj pointer
nins	The number of signal inputs.
nouts	The number of signal outputs

void eobj_dspflags	(	void *	x,
		long	flags
	)

Initializes the flags of the t_edsp.

Sets the dsp inplace (default) or not inplace. You should use this function before the call of the dsp method (in the new method for example).

Parameters

x	The edspobj pointer
flags	The dsp flags.

edsp_flags

void eobj_dspfree

(

void *

x

)

The t_edspobj deletion function.
This function should replace pd_free().

Frees the memory allocated for digital dignal processing of a t_edspobj.
This function should replace pd_free() and you shouldn't have to call eobj_free();

Parameters

x	The edspobj pointer

void eobj_resize_inputs	(	void *	x,
		long	nins
	)

Resizes the number of signal inputs of a t_edspobj.

Allocates or free the signal inputs. The method can be called after the allocation of the object.

Parameters

x	The edspobj pointer.
nins	The number of signal inputs.

t_sample* eobj_getsignalinput	(	void *	x,
		long	index
	)

Retrieves the pointer to the signal of an input.

Retrieves the pointer to the signal vector of an input.
The can function can only be used during the dsp method call.

Parameters

x	The edspobj pointer.
index	The index of the input.

Returns

A pointer to the signal vector or NULL.

t_sample* eobj_getsignaloutput	(	void *	x,
		long	index
	)

Retrieves the pointer to the signal of an output.

Retrieves the pointer to the signal vector of an output.
The can function can only be used during the dsp method call.

Parameters

x	The edspobj pointer.
index	The index of the output.

Returns

A pointer to the signal vector or NULL.
