Macro Definition Documentation

H5FD_IOC

#define H5FD_IOC   (H5FDperform_init(H5FD_ioc_init))

Macro that returns the identifier for the H5FD_IOC driver. Returns a file driver identifier if successful; otherwise returns H5I_INVALID_HID.

H5FD_IOC_CURR_FAPL_VERSION

#define H5FD_IOC_CURR_FAPL_VERSION   1

The version number of the H5FD_ioc_config_t configuration structure for the H5FD_IOC driver

H5FD_IOC_DEFAULT_THREAD_POOL_SIZE

#define H5FD_IOC_DEFAULT_THREAD_POOL_SIZE   4

The default number of I/O concentrator worker threads

H5FD_IOC_FAPL_MAGIC

#define H5FD_IOC_FAPL_MAGIC   0xFED21331

Unique number used to distinguish the H5FD_IOC driver from other HDF5 file drivers

H5FD_IOC_NAME

#define H5FD_IOC_NAME   "ioc"

The canonical name for the H5FD_IOC driver

H5FD_IOC_THREAD_POOL_SIZE

#define H5FD_IOC_THREAD_POOL_SIZE   "H5FD_IOC_THREAD_POOL_SIZE"

Macro for name of the environment variable that controls/overrides the number of I/O concentrator worker threads

The value set for this environment variable is interpreted as an int value and must be > 0.
