Name: H5Pset_fclose_degree
Signature:
herr_t H5Pset_fclose_degree( hid_t fapl_id, H5F_close_degree_t fc_degree )

Purpose:
Sets the file close degree.

Description:
H5Pset_fclose_degree sets the file close degree property fc_degree in the file access property list fapl_id.

The value of fc_degree determines how aggressively H5Fclose deals with objects within a file that remain open when H5Fclose is called to close that file. fc_degree can have any one of four valid values:

Degree name H5Fclose behavior with no open object in file H5Fclose behavior with open object(s) in file
H5F_CLOSE_WEAK Actual file is closed. Access to file identifier is terminated; actual file close is delayed until all objects in file are closed
H5F_CLOSE_SEMI Actual file is closed. Function returns FAILURE
H5F_CLOSE_STRONG Actual file is closed. All open objects remaining in the file are closed then file is closed
H5F_CLOSE_DEFAULT The VFL driver chooses the behavior. Currently, all VFL drivers set this value to H5F_CLOSE_WEAK, except for the MPI-I/O driver, which sets it to H5F_CLOSE_SEMI.

Note that if a file is opened multiple times without being closed, each open operation must use the same file close degree setting. For example, if a file is already open with H5F_CLOSE_WEAK, an H5Fopen call with H5F_CLOSE_STRONG will fail.

Parameters:
hid_t fapl_id IN: File access property list identifier.
H5F_close_degree_t fc_degree     IN: Pointer to a location containing the file close degree property, the value of fc_degree.

Returns:
Returns a non-negative value if successful. Otherwise returns a negative value.
