typedef int H5FD_class_value_t |
typedef enum H5F_mem_t H5FD_mem_t |
enum H5FD_file_image_op_t |
Define enum for the source of file image callbacks
Allows querying a VFD ID for features before the file is opened.
[in] | driver_id | Virtual File Driver (VFD) ID |
[out] | flags | VFD flags supported |
Queries a virtual file driver (VFD) for feature flags. Takes a VFD hid_t so it can be used before the file is opened. For example, this could be used to check if a VFD supports SWMR.
