Detailed Description

String formatting functions used by Bond.

By default, snprintf and vsnprintf are brought into the Bond namespace from the C++ standard library. They can be replaced, e.g. with stb_sprintf, by defining USER_BOND_CSTDIO_HEADER. A replacement must declare both functions in the Bond namespace with the standard semantics. Bond passes the format strings of OutputStream::Print through to vsnprintf, so a replacement must support every conversion that Bond and its embedders use, including the BOND_PRI* macros.

File I/O is not covered here. It is abstracted by the InputStream, OutputStream and StreamFactory interfaces instead.
