is_timeout()

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

false	ok
true	error

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

false	ok
true	Fatal error; mysys/dbug functions can't be used

my_thread_is_inited()

bool my_thread_is_inited

(

)

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_self_setname()

void my_thread_self_setname

(

const char *

name

)

Sets the name of the thread for system and debugger, if possible.

Parameters

name	Name to set, must be shorter than SETNAME_MAX_LENGTH, including NULL character.

my_thread_yield()

static void my_thread_yield ( )

operator!=()

bool operator!= ( const my_thread_handle &  a, const my_thread_handle &  b  )

operator==()

bool operator== ( const my_thread_handle &  a, const my_thread_handle &  b  )
