Arrays are encoded as types of kind CTF_K_ARRAY in a ctf_stype_t.
Both size and kind for arrays are zero. The variable-length data is a
ctf_array_t: vlen in the info word should be disregarded and is
always zero.
typedef struct ctf_array
{
uint32_t cta_contents;
uint32_t cta_index;
uint32_t cta_nelems;
} ctf_array_t;
| Offset | Name | Description |
|---|---|---|
| 0x0 | uint32_t cta_contents
| The type of the array elements: a type ID. |
| 0x4 | uint32_t cta_index
| The type of the array index: a type ID of an integral type.
If this is a variable-length array, the index type ID will be 0
(but the actual index type of this array is probably int).
Probably redundant and may be dropped in v4. |
| 0x8 | uint32_t cta_nelems
| The number of array elements. 0 for VLAs, and also for
the historical variety of VLA which has explicit zero dimensions (which will
have a nonzero cta_index.) |
The size of an array can be computed by simple multiplication of the size of the
cta_contents type by the cta_nelems.
