What is the UI equivalent for PTHREAD_MUTEX_INITALIZER?
From the man page (man mutex_init): Solaris Initialize The equivalent Solaris API used to initialize a mutex so that it has several different types of behavior is the type argument passed to mutex_init(). No current type uses arg although a future type may specify additional behavior parameters via arg. type may be one of the following: USYNC_THREAD The mutex can synchronize threads only in this process. arg is ignored. The USYNC_THREAD Solaris mutex type for pro- cess scope is equivalent to the POSIX mutex attribute setting PTHREAD_PROCESS_PRIVATE. USYNC_PROCESS The mutex can synchronize threads in this process and other processes. Only one process should initialize the mutex. arg is ignored. The USYNC_PROCESS Solaris mutex type for process scope is equivalent to the POSIX mutex attribute setting PTHREAD_PROCESS_SHARED. The object initialized with this attribute must be allocated in memory shared between processes, i.e. either in Sys V shared memory (see shmop(2)). or in memory mapped
