Function
GLibbit_lock
since: 2.24
Declaration [src]
void
g_bit_lock (
volatile gint* address,
gint lock_bit
)
Description [src]
Sets the indicated lock_bit
in address
. If the bit is already
set, this call will block until g_bit_unlock()
unsets the
corresponding bit.
Attempting to lock on two different bits within the same integer is not supported and will very probably cause deadlocks.
The value of the bit that is set is (1u << bit
). If bit
is not
between 0 and 31 then the result is undefined.
This function accesses address
atomically. All other accesses to
address
must be atomic in order for this function to work
reliably. While address
has a volatile
qualifier, this is a historical
artifact and the argument passed to it should not be volatile
.
