What is the difference: sprintf and wsprintf ?

[cnlai]

I keep thinking what is the difference between "sprintf" and "wsprintf"
in terms of usage ?

thanks.

swprintf is for wide characters(I think)

Good think.

To clarify _and_ confuse:
wsprintf is a similar function that accepts TCHAR arguments (switches
depending on whether UNICODE is defined), and has somewhat different
behavior.

sprintf is implemented by the C runtime. wsprintfA (aka wsprintf if you're
writing an ANSI application) is implemented in USER32 by Windows. wsprintf
can output a maximum of 1024 characters and can't handle floats or doubles.

Similarly, swprintf is C, whereas wsprintfW (aka wsprintf if you're writing
a Unicode app) is Windows.
