cxl_adapter_next - iterate to the next CXL adapter
cxl_for_each_adapter - iteration macro
struct cxl_adapter_h *cxl_adapter_next(struct cxl_adapter_h *adapter);
cxl_adapter_next() returns an adapter handle describing the next available CXL adapter.
When adapter is NULL, then an adapter handle is allocated, and the first available adapter is returned.
When adapter is the last CXL adapter available, then the adapter handle is freed, errno is set to zero, and NULL is returned. Alternatively, the adapter handle can be freed explicitly with cxl_adapter_free().
On success, an adapter handle is returned, or NULL is returned and errno is set to zero. On error, NULL is returned, and errno is set appropriately.
The CXL library provides the following macro to enumerate all CXL adapters:
#define cxl_for_each_adapter(adapter) \
for (adapter = cxl_adapter_next(NULL); adapter; \
adapter = cxl_adapter_next(adapter))
cxl(3), cxl_adapter_afu_next(3), cxl_adapter_dev_name(3), cxl_adapter_free(3), cxl_afu_next(3), cxl_get_base_image(3), cxl_get_caia_version(3), cxl_get_image_loaded(3), cxl_get_psl_revision(3), cxl_get_psl_timebase_synced(3), cxl_get_tunneled_ops_supported(3)
