This module contains various utility functions that extend the basic utility functions provided by the GLib library.
void exo_noop (void);
This function has no effect. It does nothing but returning instantly. It is mostly useful in situations that require a function to be called, but that function does not need to do anything useful.
Since 0.3.1
gint exo_noop_one (void);
This function has no effect but simply returns
the integer value 1
. It is mostly useful in
situations where you just need a function that
returns 1
, but don't want to perform any other
actions.
Returns : |
the integer value 1 .
|
Since 0.3.1
gint exo_noop_zero (void);
This function has no effect but simply returns
the integer value 0
. It is mostly useful in
situations where you just need a function that
returns 0
, but don't want to perform any other
actions.
Returns : |
the integer value 0 .
|
Since 0.3.1
gpointer exo_noop_null (void);
This function has no effect but simply returns
a NULL
pointer. It is mostly useful in
situations where you just need a function that
returns NULL
, but don't want to perform any
other actions.
Returns : |
a NULL pointer.
|
Since 0.3.1
gboolean exo_noop_true (void);
This function has no effect, but simply returns
the boolean value TRUE
. It is mostly useful in
situations where you just need a function that
returns TRUE
, but don't want to perform any
other actions.
Returns : |
the boolean value TRUE .
|
Since 0.3.1
gboolean exo_noop_false (void);
This function has no effect, but simply returns
the boolean value FALSE
. It is mostly useful in
situations where you just need a function that
returns FALSE
, but don't want to perform any
other actions.
Returns : |
the boolean value FALSE .
|
Since 0.3.1
void exo_atomic_inc (gint *value);
Increments the integer at value
by one in an
atomic fashion. The advantage over using
g_atomic_int_inc()
is that calls to this
function can be inlined.
|
a pointer to the integer value to increment. |
Since 0.3.1
gboolean exo_atomic_dec (gint *value);
Decrements the integer at value
by one in an atomic
fashion and returns TRUE
if the value
dropped to
zero by this operation, else FALSE
. The advantage
over using g_atomic_int_dec()
is that calls to this
function can be inlined.
|
a pointer to the integer value to decrement. |
Returns : |
%TRUE if value dropped to zero, else FALSE .
