GLibMutexinit

Initializes a GMutex so that it can be used.

This function is useful to initialize a mutex that has been allocated on the stack, or as part of a larger structure. It is not necessary to initialize a mutex that has been statically allocated.

  typedef struct {
    GMutex m;
    ...
  } Blob;

Blob *b;

b = g_new (Blob, 1);
g_mutex_init (&b->m);

To undo the effect of g_mutex_init() when a mutex is no longer needed, use g_mutex_clear().

Calling g_mutex_init() on an already initialized GMutex leads to undefined behaviour.
