==Description==
This function is used to write a large amount of data to an INI file. It by-passes NSIS_MAX_STRLEN (1024 by default, or 8192 when using the NSIS special build) by writing pieces of data individually rather than all at once as one sring.

==Usage==
<highlight-nsis>
${WriteINILargeStr_Open} "$INSTDIR\file.ini" "Section" "Key"
Push " Stuart!"
Push " my name is"
Push "Hello"
${WriteINILargeStr_Close}
</highlight-nsis>
The data is written into the file in seperate pieces (per Push instruction) and must be Pushed in reverse order to how they must be written to the file (due to stack function limitations).
This will write to file.ini with the following data:

'''[Section]'''<br />
'''Key=Hello my name is Stuart!'''

==The Function==
Copy the following code into Notepad and save it as WriteINILargeStr.nsh under Include. Make sure you select All files (*.*) as the Save as type first. You can then use the function after using:<br />''!include WriteINILargeStr.nsh''
