◆ my_thread_attr_setstacksize()

static int my_thread_attr_setstacksize ( my_thread_attr_t attr,
size_t  stacksize 
)

◆ my_thread_cancel()

int my_thread_cancel ( my_thread_handle thread)

◆ my_thread_create()

int my_thread_create ( my_thread_handle thread,
const my_thread_attr_t attr,
my_start_routine  func,
void *  arg 
)

◆ my_thread_end()

void my_thread_end ( )

Deallocate memory used by the thread for book-keeping.

Note
This may be called multiple times for a thread. This happens for example when one calls 'mysql_server_init()' mysql_server_end() and then ends with a mysql_end().

◆ my_thread_equal()

static int my_thread_equal ( my_thread_t  t1,
my_thread_t  t2 
)
inlinestatic

◆ my_thread_exit()

void my_thread_exit ( void *  value_ptr)

◆ my_thread_global_end()

void my_thread_global_end ( )

◆ my_thread_global_init()

bool my_thread_global_init ( )

initialize thread environment

Return values
falseok
trueerror

◆ my_thread_global_reinit()

void my_thread_global_reinit ( )

Re-initialize components initialized early with my_thread_global_init.

Some mutexes were initialized before the instrumentation. Destroy + create them again, now that the instrumentation is in place. This is safe, since this function() is called before creating new threads, so the mutexes are not in use.

◆ my_thread_init()

bool my_thread_init ( )

Allocate thread specific memory for the thread, used by mysys and dbug.

Note
This function may called multiple times for a thread, for example if one uses my_init() followed by mysql_server_init().
Return values
falseok
trueFatal error; mysys/dbug functions can't be used

◆ my_thread_join()

int my_thread_join ( my_thread_handle thread,
void **  value_ptr 
)

◆ my_thread_self()

static my_thread_t my_thread_self ( )
inlinestatic

◆ my_thread_yield()

static void my_thread_yield ( )
