Chapter Eleven — SGML Functions (continued)
A series of functions are provided to allow for easy access and modification of the header section of an HTML file or document.
The principal areas of access are: the DTD, meta information, CSS information, scripts, links and the title of the document.
These functions are presently in beta release. Functions marked with ‡ are shown for a future release. In addition, other functions are planned.
To use the header functions, a header must be “mapped” by creating an HTML Header Object and specifying a file or a handle to a file like object such as a Mapped Text Object. The HTMLHeaderOpen function maps the data and returns a handle. The CloseHandle function is used to release the object. Closing the handle does not apply any changes to the header.
The header components can then be inspected and changed. Once ready to commit the HTMLHeaderWrite function is called to write a complete header or each section can be updated individually.
