H5ES_GET_ERR_INFO retrieves information about failed operations in an event set specified by es_id.  The strings retrieved for each error info must be released by calling H5_FREE_MEMORY.

Below is the description of the H5ES_err_info_t structure:

typedef struct H5ES_err_info_t {

    char * api_name;       /* Name of HDF5 API routine called */

    char * api_args;       /* "Argument string" for arguments to HDF5 API routine called */

    char * app_file_name;  /* Name of source file where the HDF5 API routine was called */ 

    char * app_func_name;  /* Name of function where the HDF5 API routine was called */

    unsigned app_line_num; /* Line # of source file where the HDF5 API routine was called */

    uint64_t op_ins_count; /* Counter of operation's insertion into event set */

    uint64_t op_ins_ts;    /* Timestamp for when the operation was inserted into the event set */ 

    hid_t err_stack_id;    /* ID for error stack from failed operation */

} H5ES_err_info_t;

Returns a non-negative value if successful; otherwise returns a negative value.
