#define SPA_TYPE_INTERFACE_ThreadUtils   SPA_TYPE_INFO_INTERFACE_BASE "ThreadUtils"

◆ SPA_VERSION_THREAD_UTILS

#define SPA_VERSION_THREAD_UTILS   0

◆ SPA_VERSION_THREAD_UTILS_METHODS

#define SPA_VERSION_THREAD_UTILS_METHODS   0

◆ SPA_KEY_THREAD_NAME

#define SPA_KEY_THREAD_NAME   "thread.name" /* the thread name */

◆ SPA_KEY_THREAD_STACK_SIZE

#define SPA_KEY_THREAD_STACK_SIZE   "thread.stack-size" /* the stack size of the thread */

Function Documentation

◆ spa_thread_utils_drop_rt()

static int spa_thread_utils_drop_rt ( struct spa_thread_utils * o,
struct spa_thread * thread )
inlinestatic
