#define ipatch_sample_store_get_format(store)
Macro for getting the sample format from a sample store. No lock is required since format can only be set prior to the store being actively used.
Returns : |
Sample format field. See sample. |
#define ipatch_sample_store_get_size(store) ((store)->size)
Macro for getting the sample size in frames of a sample store. No lock is required since size can only be set prior to the store being actively used.
Returns : |
Sample store size in frames. |
#define ipatch_sample_store_get_rate(store) ((store)->rate)
Macro for getting the sample rate from a sample store. No lock is required since rate can only be set prior to the store being actively used.
Returns : |
Sample rate in HZ. |
#define ipatch_sample_store_get_size_bytes(store)
Macro for getting the sample store data size in bytes. No lock is required since format and size can only be set prior to the store being actively used.
Returns : |
Sample store size in bytes. |
IpatchSampleStore * ipatch_sample_store_first (IpatchIter *iter);
Gets the first item in a sample store iterator. A convenience wrapper for
ipatch_iter_first().
|
Patch item iterator containing IpatchSampleStore items |
Returns : |
The first sample store in iter or NULL if empty.
|
IpatchSampleStore * ipatch_sample_store_next (IpatchIter *iter);
Gets the next item in a sample store iterator. A convenience wrapper for
ipatch_iter_next().
|
Patch item iterator containing IpatchSampleStore items |
Returns : |
The next sample store in iter or NULL if at the end of the list.
