Changeset 37f4c2d in rtems for c/src/lib/libbsp/unix/posix/clock

Timestamp:

Author:

Joel Sherrill <joel.sherrill@…>

Branches:

4.10, 4.11, 4.8, 4.9, 5, master

Parents:

Message:

Modified UNIX simulator port so all references to native unix
stuff is in the executive source proper in the file cpu.c. This
should help avoid conflicts between RTEMS POSIX files and UNIX files.

• c/src/lib/libbsp/unix/posix/clock/clock.c (modified) (6 diffs)
