◆ sys_thread_new()

sys_thread_t sys_thread_new ( const char name,
lwip_thread_fn  thread,
void arg,
int  stacksize,
int  prio 
)

The only thread function: Starts a new thread named "name" with priority "prio" that will begin its execution in the function "thread()". The "arg" argument will be passed as an argument to the thread() function. The stack size to used for this thread is the "stacksize" parameter. The id of the new thread is returned. Both the id and the priority are system dependent. ATTENTION: although this function returns a value, it MUST NOT FAIL (ports have to assert this!)

Parameters
namehuman-readable name for the thread (used for debugging purposes)
threadthread-function
argparameter passed to 'thread'
stacksizestack size in bytes for the new thread (may be ignored by ports)
priopriority of the new thread (may be ignored by ports)
