Macro Definition Documentation

TIME_ID

#define TIME_ID

(

i

)

((i)*(b->nx+1))

Macro to get the id in tx array corresponding to index (assuming b->nx exist)

Function Documentation

mbs_anim_write()

int mbs_anim_write

(

MbsBuffer *

b

)

Write the content of the q buffer as anim file to the disk.

Returns

error (0 if no error)

mbs_buffer_save()

int mbs_buffer_save	(	MbsBuffer *	b,
		double	t,
		double *	x
	)

Save the given array to the specified buffer with the specified time.

The content of the buffer is automatically written to the associated file when the buffer is full. The buffer index is then reset to 0.

Parameters

b	the buffer in which to store
t	the corresponding time [s]
x	the array to save (value are copied)

Returns

error (0 if no error)

mbs_buffer_write()

int mbs_buffer_write

(

MbsBuffer *

b

)

Write the content of the buffer to disk.

Values contained in the buffer for line 0 to line index-1 are appended to the file associated with this buffer.

Returns

error (0 if no error)

mbs_delete_buffer()

void mbs_delete_buffer

(

MbsBuffer *

b

)

Free memory of the specified MbsBuffer.

mbs_delete_growing_buffer()

void mbs_delete_growing_buffer

(

MbsGrowingBuffer *

b

)

release memory for growing buffer

Parameters

[out]

b

growing buffer to release

mbs_growing_buffer_save()

int mbs_growing_buffer_save	(	MbsGrowingBuffer *	b,
		double	t
	)

Save the given values of auto_output to the specified buffer with the specified time.

Parameters

[in,out]	b	the growing buffer in which to store
[in]	t	the corresponding time [s]

The content of the buffer is automatically written to the associated file when the buffer is full. The buffer index is then reset to 0.

Returns

error (0 if no error)

mbs_growing_buffer_write()

int mbs_growing_buffer_write

(

MbsGrowingBuffer *

b

)

write the content of the growing buffer to disk

Parameters

[in]

b

growing buffer

Returns

error (0 if no error)

mbs_new_buffer()

MbsBuffer* mbs_new_buffer	(	char *	filename,
		char *	anim_name,
		int	nx,
		int	size,
		int	id,
		char *	buf_format,
		int	save_anim,
		int	save_visu,
		double	anim_period
	)

Allocate and initialize a MbsBuffer structure.

The associated text file defined by filename is (re-)initialized

Parameters

[in]	filename	the name of the file associated to this buffer
[in]	anim_name	the name of the file associated to the animation file (only used for BUFFER_Q)
[in]	nx	the size of the array to be tracked by this buffer
[in]	size	the size of the buffer
[in]	id	the buffer ID, see BUFFER_Q, BUFFER_QD ...
[in]	format	of the buffer (if NULL, "%e" is used)
[in]	save_anim	1 to save the anim file, 0 otherwise
[in]	save_visu	1 to save the visualization file (as it appears in 'user_realtime_visu.c'), 0 otherwise (for real-time simulation)
[in]	anim_period	time interval between two recorded values in the animation file

mbs_new_growing_buffer()

MbsGrowingBuffer* mbs_new_growing_buffer	(	int	max_nx,
		int	size,
		const char *	respath
	)

create a new growing buffer for the user inputs to save

Parameters

[in]	max_nx	maximum number of user inputs to save
[in]	size	size of the buffer
[in]	respath	path to the file for the results

Returns

new growing buffer initialized
