int sd_card_list_files_match	(	uint16_t	result_file_num_max,
		uint16_t	result_file_len_max,
		char	result[][result_file_len_max],
		char *	path,
		char const *const	pattern )

Finds all files on SD card that match the given pattern.

Note

The function uses a recursive approach with internal buffers. Memory intensive.

Parameters

[in]	result_file_num_max	Maximum number of files to be found.
[in]	result_file_len_max	Maximum length of each file name including total path length
[out]	result	Pointer to the result array of dimension result_file_num_max result_file_len_max.
[in]	path	NULL, search from root, otherwise search from the given path. Note not to add an ending "/"
[in]	pattern	Null terminated pattern to find, e.g. *.lc3 or *.wav

Return values
