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.
value : | 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.
value : | a pointer to the integer value to decrement. |
Returns : | TRUE if value dropped to zero, else FALSE. |
Since 0.3.1
