Author: pfg Date: Sat Aug 18 01:05:38 2018 New Revision: 337992 URL: https://svnweb.freebsd.org/changeset/base/337992 Log: POSIX compliance improvements in the pthread(3) functions. This basically adds makes use of the C99 restrict keyword, and also adds some 'const's to four threading functions: pthread_mutexattr_gettype(), pthread_mutexattr_getprioceiling(), pthread_mutexattr_getprotocol(), and pthread_mutex_getprioceiling. The changes are in accordance to POSIX/SUSv4-2018.
