The funcs xbps_pkg_name() and xbps_pkgpattern_name() were using malloc(3) to return the result, until now. They now have been changed to not allocate the result via malloc, the caller is responsible to provide a buffer at least of XBPS_NAME_SIZE (64). If for whatever reason the pkgname can't be guessed, returns false. This should avoid lots of small allocs around libxbps. New functions have the following prototype: bool xbps_pkg_name(char *dst, size_t len, const char *pkg) bool xbps_pkgpattern_name(char *dst, size_t len, const char *pkg) as suggested by @duncaen.
