void	sys_mutex_free (sys_mutex_t *mutex)

Detailed Description

Mutexes are recommended to correctly handle priority inversion, especially if you use LWIP_CORE_LOCKING .

Function Documentation

◆ sys_mutex_free()

void sys_mutex_free ( sys_mutex_t * mutex )

Delete a semaphore

Parameters

mutex the mutex to delete

Definition at line 355 of file sys_arch.cc.

Referenced by tcpip_shutdown().

Here is the caller graph for this function:

◆ sys_mutex_lock()

void sys_mutex_lock ( sys_mutex_t * mutex )

Lock a mutex

Parameters

mutex the mutex to lock

Definition at line 344 of file sys_arch.cc.

References Semaphore::acquire().

Referenced by mem_malloc().

Here is the caller graph for this function:

◆ sys_mutex_new()

err_t sys_mutex_new ( sys_mutex_t * mutex )

Create a new mutex. Note that mutexes are expected to not be taken recursively by the lwIP code, so both implementation types (recursive or non-recursive) should work.

Parameters

mutex pointer to the mutex to create
