Member Function Documentation

void H5::H5Library::open (   )  [static]

Initializes the HDF5 library. Exceptions: H5::LibraryIException

void H5::H5Library::close (   )  [static]

Flushes all data to disk, closes files, and cleans up memory. Exceptions: H5::LibraryIException

void H5::H5Library::dontAtExit (   )  [static]

Instructs library not to install atexit cleanup routine. Exceptions: H5::LibraryIException

void H5::H5Library::getLibVersion (  unsigned &  majnum, unsigned &  minnum, unsigned &  relnum )  [static]

Returns the HDF library release number. Parameters: majnum  - OUT: Major version of the library minnum  - OUT: Minor version of the library relnum  - OUT: Release number of the library Exceptions: H5::LibraryIException

void H5::H5Library::checkVersion (  unsigned  majnum, unsigned  minnum, unsigned  relnum )  [static]

Verifies that the arguments match the version numbers compiled into the library. Parameters: majnum  - IN: Major version of the library minnum  - IN: Minor version of the library relnum  - IN: Release number of the library Exceptions: H5::LibraryIException  Description For information about library version, please refer to the C layer Reference Manual at: ../RM_H5.html#Library-VersCheck

void H5::H5Library::garbageCollect (   )  [static]

Walks through all the garbage collection routines for the library, which are supposed to free any unused memory they have allocated. Exceptions: H5::LibraryIException  Description It is not required that H5Library::garbageCollect be called at any particular time; it is only necessary in certain situations, such as when the application has performed actions that cause the library to allocate many objects. The application should call H5Library::garbageCollect if it eventually releases those objects and wants to reduce the memory used by the library from the peak usage required. The library automatically garbage collects all the free lists when the application ends.

void H5::H5Library::setFreeListLimits (  int  reg_global_lim, int  reg_list_lim, int  arr_global_lim, int  arr_list_lim, int  blk_global_lim, int  blk_list_lim )  [static]

Sets limits on the different kinds of free lists. Parameters: reg_global_lim  - IN: Limit on all "regular" free list memory used reg_list_lim  - IN: Limit on memory used in each "regular" free list arr_global_lim  - IN: Limit on all "array" free list memory used arr_list_lim  - IN: Limit on memory used in each "array" free list blk_global_lim  - IN: Limit on all "block" free list memory used blk_list_lim  - IN: Limit on memory used in each "block" free list Exceptions: H5::LibraryIException  Description Setting a value of -1 for a limit means no limit of that type. For more information on free list limits, please refer to C layer Reference Manual at: ../RM_H5.html#Library-SetFreeListLimits
