Overview
|
|
--------
|
|
|
|
This module offers Espressif specific extensions to the pthread library that can be used to influence the behaviour of pthreads. Currently the following configuration can be tuned:
|
|
* Stack size of the pthreads
|
|
* Priority of the created pthreads
|
|
* Inheriting this configuration across threads
|
|
* Thread name
|
|
* Core affinity / core pinning.
|
|
|
|
Example to tune the stack size of the pthread:
|
|
|
|
.. code-block:: c
|
|
|
|
void * thread_func(void * p)
|
|
{
|
|
printf("In thread_func\n");
|
|
return NULL;
|
|
}
|
|
|
|
void app_main(void)
|
|
{
|
|
pthread_t t1;
|
|
|
|
esp_pthread_cfg_t cfg = esp_create_default_pthread_config();
|
|
cfg.stack_size = (4 * 1024);
|
|
esp_pthread_set_cfg(&cfg);
|
|
|
|
pthread_create(&t1, NULL, thread_func);
|
|
}
|
|
|
|
The API can also be used for inheriting the settings across threads. For example:
|
|
|
|
.. code-block:: c
|
|
|
|
void * my_thread2(void * p)
|
|
{
|
|
/* This thread will inherit the stack size of 4K */
|
|
printf("In my_thread2\n");
|
|
|
|
return NULL;
|
|
}
|
|
|
|
void * my_thread1(void * p)
|
|
{
|
|
printf("In my_thread1\n");
|
|
pthread_t t2;
|
|
pthread_create(&t2, NULL, my_thread2);
|
|
|
|
return NULL;
|
|
}
|
|
|
|
void app_main(void)
|
|
{
|
|
pthread_t t1;
|
|
|
|
esp_pthread_cfg_t cfg = esp_create_default_pthread_config();
|
|
cfg.stack_size = (4 * 1024);
|
|
cfg.inherit_cfg = true;
|
|
esp_pthread_set_cfg(&cfg);
|
|
|
|
pthread_create(&t1, NULL, my_thread1);
|
|
}
|
