StgIsStorageILockBytes

Indicates whether the specified byte array contains a storage object.

WINOLEAPI StgIsStorageILockBytes(

ILockBytes * plkbyt

//ILockBytes pointer to the byte array to be examined

);

Parameter

plkbyt: ILockBytes pointer to the byte array to be examined.

Return Values

S_OK: Indicates the specified byte array contains a storage object.
S_FALSE: Indicates the specified byte array does not contain a storage object.

File system errors.

ILockBytes interface error return values.

Remarks

At the beginning of the byte array underlying a storage object is a signature distinguishing a storage object (supporting the IStorage interface) from other file formats. The StgIsStorageILockBytes function is useful to applications whose documents use a byte array (a bye array object supports the ILockBytes interface) that might or might not use storage objects.
