coml2api.h contains the following programming interfaces:
Functions
| CreateILockBytesOnHGlobal Creates a byte array object that uses an HGLOBAL memory handle to store the bytes intended for in-memory storage of a compound file. |
| FmtIdToPropStgName Converts a property set format identifier (FMTID) to its storage or stream name. |
| GetConvertStg The GetConvertStg function returns the current value of the convert bit for the specified storage object. |
| GetHGlobalFromILockBytes The GetHGlobalFromILockBytes function retrieves a global memory handle to a byte array object created using the CreateILockBytesOnHGlobal function. |
| PropStgNameToFmtId Converts a property set storage or stream name to its format identifier. |
| ReadClassStg The ReadClassStg function reads the CLSID previously written to a storage object with the WriteClassStg function. |
| ReadClassStm Reads the CLSID previously written to a stream object with the WriteClassStm function. |
| StgCreateDocfile Creates a new compound file storage object using the COM-provided compound file implementation for the IStorage interface. |
| StgCreateDocfileOnILockBytes Creates and opens a new compound file storage object on top of a byte-array object provided by the caller. |
| StgCreatePropSetStg Creates a property set storage object from a specified storage object. |
| StgCreatePropStg Creates and opens a property set in a specified storage or stream object. |
| StgCreateStorageEx Creates a new storage object using a provided implementation for the IStorage or IPropertySetStorage interfaces. |
| StgIsStorageFile The StgIsStorageFile function indicates whether a particular disk file contains a storage object. |
| StgIsStorageILockBytes The StgIsStorageILockBytes function indicates whether the specified byte array contains a storage object. |
| StgOpenPropStg Opens a specified property set in a specified storage or stream object. |
| StgOpenStorage Opens an existing root storage object in the file system. |
| StgOpenStorageEx Opens an existing root storage object in the file system. Use this function to open Compound Files and regular files. |
| StgOpenStorageOnILockBytes The StgOpenStorageOnILockBytes function opens an existing storage object that does not reside in a disk file, but instead has an underlying byte array provided by the caller. |
| StgSetTimes The StgSetTimes function sets the creation, access, and modification times of the indicated file, if supported by the underlying file system. |
| WriteClassStg The WriteClassStg function stores the specified class identifier (CLSID) in a storage object. |
| WriteClassStm The WriteClassStm function stores the specified CLSID in the stream. |
Structures
| STGOPTIONS Specifies features of the storage object, such as sector size, in the StgCreateStorageEx and StgOpenStorageEx functions. |
