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.
