Configuration structure for H5Pset_fapl_ioc() / H5Pget_fapl_ioc()
H5FD_ioc_config_t is a public structure that is used to pass configuration data to the H5FD_IOC driver via a File Access Property List. A pointer to an instance of this structure is a parameter to H5Pset_fapl_ioc() and H5Pget_fapl_ioc().
Data Fields | |
uint32_t | magic |
uint32_t | version |
int32_t | thread_pool_size |
uint32_t magic |
A somewhat unique number which distinguishes the H5FD_IOC driver from other drivers. Used in combination with a version number, it can help to validate a user-generated File Access Property List. This field should be set to H5FD_IOC_FAPL_MAGIC.
int32_t thread_pool_size |
The number of I/O concentrator worker threads to use.
This value can also be set or adjusted with the H5FD_IOC_THREAD_POOL_SIZE environment variable.
uint32_t version |
Version number of the H5FD_ioc_config_t structure. Any instance passed to H5Pset_fapl_ioc() / H5Pget_fapl_ioc() must have a recognized version number or an error will be raised. Currently, this field should be set to H5FD_IOC_CURR_FAPL_VERSION.
