alen¶

Returns the number of elements in the array.

#define alen(a) cf_array_len(a)

Parameters	Description
x	The x position of the window.
y	The y position of the window.

Code Example¶

Creating an array, adding an element, then decrementing the count to zero before freeing the array.

dyna int a = NULL;
apush(a, 5);
CF_ASSERT(alen(a) == 1);
alen(a)--;
CF_ASSERT(alen(a) == 0);
afree(a);

a must not by NULL. This function returns a proper l-value, so you can assign to it, i.e. increment/decrement can be quite useful.
