> INT32 HTMLExportFilter::Write(TCHAR* pcToWrite, CCLexFile* pfileToWrite, TCHAR* pcBuffer)
Author: Graham_Walmsley (Xara Group Ltd) <*****@*****.**>
Created: 9/4/97
Inputs: pcToWrite The string to write
pfileToWrite The file to write to (may be NULL)
pcBuffer The text buffer to write to (may be NULL)
Returns: The number of TCHARs written
Purpose: Writes the specified string to the file, or the text buffer,
or both, or neither.
This function returns the number of TCHARS written. So you
can call this function first with all parameters NULL to find out
the length of the text buffer you need, then set up that text buffer,
then call this function again to write to that text buffer.
Note that this should be the *only* function that actually writes
to the file. All other write functions must call this one. That's
because this function handles the word wrapping.
Notes: This is how the word wrapping works:
First this function writes out the string passed to it (e.g. "<HTML>").
It does not put any EOLs in the middle of this string.
Then it checks to see if word wrapping is turned on (from our
member flag m_fShouldWordWrap).
If so, it checks to see if the number of characters written on the
line so far is greater than the word wrap limit.
If so, this function puts an EOL line after the string that has
been written.
Note that, if you write an end of line string ("\r\n") directly to
the write function without calling WriteEOL, the word wrapping
will not work properly.

Created: 22nd April 1993
Inputs: A pointer to the format string, a variable-parameter pointer to the

StringBase::BuildList and scans through it, formatting stack-frame
parameters according to their list entry. This produces another list,
this time of formatted parameters, which is then concatenated to
produce the final output.
