The HPENDATA Object
An application accesses ink data with HPENDATA, which stands for "a handle to pen data." Windows stores the pen data in a
block of memory, called the HPENDATA object. This data structure is analogous to the other Window "H" data types
such as HDC, HCURSOR, and HPEN. HPENDATA shares certain similarities with these data types:
- The handle references an internal data structure that resides in memory.
- Windows provides various API functions that operate on the data.
- Developers should ignore the details of the underlying data structure and use
the API functions alone to perform the required work.
The remainder of this chapter discusses the HPENDATA object and the API functions used to manipulate the data it contains.
