traditionally, our cfsetispeed just set the output speed. this was not conforming or reasonable behavior. use of the input baud bits in termios c_cflag depends on kernel support, which was added to linux along with TCSETS2 ioctl and arbitrary-baud functionality sometime in the 2.6 series. with older kernels, the separate input baud will not take, but this is the best behavior we can hope for anyway, certainly better than wrongly clobbering output baud setting. the nonstandard cfsetspeed is now moved to a separate file, since it no longer admits the weak alias implementation that made it namespace-safe. it now sets the output speed, and on success, sets the input speed to 0 (matched to output).
musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
