contin_array_create()

int contin_array_create	(	void *	pcm_cont,
		uint32_t	pcm_cont_size,
		void const *const	pcm_finite,
		uint32_t	pcm_finite_size,
		uint32_t *const	finite_pos )

#include <include/contin_array.h>

Creates a continuous array from a finite array.

Parameters

pcm_cont	Pointer to the destination array.
pcm_cont_size	Size of pcm_cont.
pcm_finite	Pointer to an array of samples or data.
pcm_finite_size	Size of pcm_finite.
finite_pos	Variable used internally. Must be set to 0 for the first run and not changed.

Note

This function serves the purpose of e.g. having a set of audio samples stored in pcm_finite. This can then be fetched in smaller pieces into ram and played back in a loop using the results in pcm_cont. The function keeps track of the current position in finite_pos, so that the function can be called multiple times and maintain the correct position in pcm_finite.

Return values

0	If the operation was successful.
-EPERM	If any sizes are zero.
-ENXIO	On NULL pointer.
