The information in this article applies to:

 - Microsoft Windows Software Development Kit (SDK) 3.1 
 - Microsoft Win32 Application Programming Interface (API), used with:
    - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 
    - Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 
-------------------------------------------------------------------------------

SUMMARY
=======

The wsprintf(lpOutput, lpFormat [, argument] ...) and wvsprintf() functions
format and store a series of characters and values in a buffer specified by the
first parameter, lpOutput. This buffer is limited to 1K (1024 bytes); in other
words, the largest buffer that wsprintf can use is 1K.

If an application tries to use a buffer larger than 1K, the string will be
truncated automatically to a length of 1K.
