#define ARR_APP1 (   type,
  arr,
  elt 
)    (ARR_EXTEND(type, (arr), 1), (arr)[ARR_LEN((arr))-1] = (elt))

Append one element to a flexible array.

Parameters
typeThe element type of the array.
arrThe array, which must be an lvalue.
eltThe new element, must be of type (type).

Definition at line 276 of file array.h.

#define ARR_EXTEND (   type,
  arr,
  delta

Parameters
typeThe element type of the array.
arrThe array, which must be an lvalue.
deltaThe delta number of elements.
Remarks
This macro may change arr, so update all references!

Value:
do { \
if ((n) >= ARR_LEN(arr)) { ARR_RESIZE(type, arr, (n)+1); } \
} while(0)
#define ARR_RESIZE(type, arr, n)

Parameters
typeThe element type of the array.
arrThe array, which must be an lvalue.
nThe new size of the array.
Remarks
This macro may change arr, so update all references!

#define ARR_RESIZE (   type,
  arr,
 
)    ((arr) = (type*) ir_arr_resize((void *)(arr), (n), sizeof(type)))

#define DUP_ARR_D (   type,
  obstack,
  arr 
)    ((type*)memcpy(NEW_ARR_D(type, (obstack), ARR_LEN((arr))), (arr), sizeof(type) * ARR_LEN ((arr))))

Duplicates an array and returns the new dynamic one.

Parameters
typeThe element type of the new array.
obstackAn struct obstack * were the data will be allocated
arrAn array from which the elements will be duplicated

This macro creates a dynamic array of a given type at runtime. The size of the array cannot be changed later.

Returns
A pointer to the dynamic array (can be used as a pointer to the first element of this array).

Parameters
typeThe element type of the new array.
arrAn array from which the elements will be duplicated

This macro creates a flexible array of a given type at runtime. The size of the array can be changed later.

Returns
A pointer to the flexible array (can be used as a pointer to the first element of this array).
