<H1><A NAME="FUNCTION_DESCRIPTIONS">FUNCTION DESCRIPTIONS</A></H1>
<P>
<HR>
<H2><A NAME="AllocateString">AllocateString</A></H2>
<P>
Method AllocateString allocates memory for a string and copies the source
string to that memory location (and returns it).
<P>
The format of the AllocateString method is:
<blockquote>char *AllocateString (const char *source) </blockquote>
<P>
<FONT SIZE=-1>A</FONT> description of each parameter follows:
<DL><DL>
<DT><STRONG><A NAME="item_o">allocated_string:</A></STRONG><DD>
<P>
Method AllocateString returns a copy of the source string.
<DT><STRONG>source:</STRONG><DD>
<P>
<FONT SIZE=-1>A</FONT> character string.
</DL></DL>
<P>
<HR>
<H2><A NAME="AppendImageFormat">AppendImageFormat</A></H2>
<P>
Method AppendImageFormat appends the image format type to the filename. If
an extension to the file already exists, it is first removed.
<P>
The format of the AppendImageFormat method is:
<blockquote>void AppendImageFormat (const char *format, char *filename) </blockquote>
<P>
<FONT SIZE=-1>A</FONT> description of each parameter follows.
<DL><DL>
<DT><STRONG>format:</STRONG><DD>
<P>
Specifies a pointer to an array of characters. This is the format of the
image.
<DT><STRONG>filename:</STRONG><DD>
<P>
Specifies a pointer to an array of characters. The unique file name is
returned in this array.
</DL></DL>
<P>
<HR>
<H2><A NAME="BaseFilename">BaseFilename</A></H2>
<P>
Method BaseFilename removes the path name component and any extensions.
<P>
The format of the BaseFilename function is:
<blockquote>BaseFilename (name) </blockquote>
<P>
<FONT SIZE=-1>A</FONT> description of each parameter follows:
<DL><DL>
<DT><STRONG>name:</STRONG><DD>
<P>
Specifies a pointer to a character array that contains the name.
</DL></DL>
<P>
<HR>
<H2><A NAME="CloneString">CloneString</A></H2>
<P>
Method CloneString allocates memory for the destination string and copies
the source string to that memory location.
<P>
The format of the (void) CloneString method is:
<blockquote>unsigned int CloneString (char **destination, const char *source) </blockquote>
<P>
<FONT SIZE=-1>A</FONT> description of each parameter follows:
<DL><DL>
<DT><STRONG>status:</STRONG><DD>
<P>
Method CloneString returns True is the string is cloned, otherwise False is
returned.
<DT><STRONG>destination:</STRONG><DD>
<P>
<FONT SIZE=-1>A</FONT> pointer to a character string.
<DT><STRONG>source:</STRONG><DD>
<P>
<FONT SIZE=-1>A</FONT> character string.
</DL></DL>
<P>
<HR>
<H2><A NAME="ConvertTextToUnicode">ConvertTextToUnicode</A></H2>
<P>
Method ConvertTextToUnicode converts an
<FONT SIZE=-1>ASCII</FONT> text string to Unicode and returns the Unicode
translation and the character count. Normal characters are just copied.
However, escaped hex codes are interpreted before converting to Unicode
(e.g. \0x30a3 is 12451 in the Unicode character set).
