Function

GLibbit_lock_and_get

unstable since: 2.86

Declaration [src]

void
g_bit_lock_and_get (
  gint* address,
  guint lock_bit,
  gint* out_val
)

Description [src]

Sets the indicated lock_bit in address and atomically returns the new value.

This is like g_bit_lock(), except it can atomically return the new value at address (right after obtaining the lock). Thus the value returned in out_val always has the lock_bit set.

Available since: 2.86

Type: guint

A bit value between 0 and 31.
