this change is made in preparation for adding search domains, for which higher-level code will need to parse resolv.conf. simply parsing it twice for each lookup would be one reasonable option, but the existing parser code was buggy anyway, which suggested to me that it's a bad idea to have two variants of this code in two different places. the old code in res_msend potentially misinterpreted overly long lines in resolv.conf, and stopped parsing after it found 3 nameservers, even if there were relevant options left to be parsed later in the file.
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
