Here is the call graph for this function:

test__sample_parsing()

int test__sample_parsing	(	struct test *test	__maybe_unused,
		int subtest	__maybe_unused
	)

test__sample_parsing - test sample parsing.

This function implements a test that synthesizes a sample event, parses it and then checks that the parsed sample matches the original sample. The test checks sample format bits separately and together. If the test passes %0 is returned, otherwise %-1 is returned.
