Tizen Native API
4.0
|
Abstracts platform threads, providing an uniform API. It's modelled after POSIX THREADS (pthreads), on Linux they are almost 1:1 mapping.

- Eina_Lock_Group for mutex/locking abstraction.

| Eina_Bool eina_thread_create | ( | Eina_Thread * | t, |
| Eina_Thread_Priority | prio, | ||
| int | affinity, | ||
| Eina_Thread_Cb | func, | ||
| const void * | data | ||
| ) |
Creates a new thread, setting its priority and affinity.
- Parameters:
-
[out] t where to return the thread identifier. Must not be NULL.prio thread priority to use, usually EINA_THREAD_BACKGROUND affinity thread affinity to use. To not set affinity use -1.func function to run in the thread. Must not be NULL.data context data to provide to func as first argument.
- Returns:
- EINA_TRUE if thread was created, EINA_FALSE on errors.

| Eina_Bool eina_thread_equal | ( | Eina_Thread | t1, |
| Eina_Thread | t2 | ||
| ) |
Checks if two thread identifiers are the same.
- Parameters:
-
t1 first thread identifier to compare. t2 second thread identifier to compare.
- Returns:
- EINA_TRUE if they are equal, EINA_FALSE otherwise.

| void* eina_thread_join | ( | Eina_Thread | t | ) |
Joins a currently running thread, waiting until it finishes.
This function will block the current thread until t finishes. The returned value is the one returned by t func() and may be NULL on errors. See Error to identify problems.
- Parameters:
-
t thread identifier to wait.
- Returns:
- value returned by t creation function
func()orNULLon errors. Check error with Error.

| Eina_Bool eina_thread_name_set | ( | Eina_Thread | t, |
| const char * | name | ||
| ) |
Sets the name of a given thread for debugging purposes.
This maps to the pthread_setname_np() GNU extension or similar if available. The name may be limited in size (possibly 16 characters including the null byte terminator). This is useful for debugging to name a thread so external tools can display a meaningful name attached to the thread.
- Parameters:
-
t thread to set the name of name a string to name the thread - this cannot be NULL
- Returns:
- EINA_TRUE if it succeeds in setting the name or EINA_FALSE otherwise.
- Since (EFL) :
- 1.16
- Since :

| Eina_Thread eina_thread_self | ( | void | ) |
Returns identifier of the current thread.
- Returns:
- identifier of current thread.
