According to Christopher Faylor on 5/14/2007 6:53 AM:

Then here's the revised list of functions I still think are worth exporting:

_Exit
asnprintf
dprintf
vasnprintf
vdprintf

And seeing as how Linux does not yet provide [v]asnprintf, here are my
arguments for exporting it:

http://sourceware.org/ml/newlib/2007/msg00403.html

In other words, there are several existing programs ported to cygwin that
would benefit from smaller size and slightly faster execution if asnprintf
were exposed as part of cygwin1.dll, and the size impact to cygwin1.dll to
provide this nice hook is much smaller than the impact of implementing
asnprintf in program space as a less efficient wrapper around snprintf.
