libk  Diff

Differences From Artifact [e3d3c3c357]:

• File kio/io.h — part of check-in [6479e060a3] at 2019-07-26 09:51:02 on branch trunk — major update. fix ridiculous old type size determination mechanism. mmap is still broken and i'm not sure why; the syscall does not appear to be going through correctly - see posix_mmap, kmheapa, and kcore/testbin.exe.fn (user: lexi, size: 1871) [annotate] [blame] [check-ins using]

To Artifact [8ac183a3d1]:

• File kio/io.h — part of check-in [926d05a4ce] at 2019-07-27 03:55:06 on branch trunk — add docs/manifesto for kfile; add initial kfile headers and function prototypes; update headers to include c++ extern guards so libk functions can be used from c++ (user: lexi, size: 2034) [annotate] [blame] [check-ins using]
