Wes McKinney created ARROW-1058:
-----------------------------------
Summary: [C++] Define minimalist C structs for exposing Arrow data
types to C code
Key: ARROW-1058
URL: https://issues.apache.org/jira/browse/ARROW-1058
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
This can also accompany an alternate IPC loader which does not use
{{shared_ptr<Buffer>}} or other currently-in-use tools for RAII-based object
lifetime.
For example, we would be able to expose {{arrow::StringArray}} to C code in a
struct like
{code:language=c}
typedef struct {
int64_t length;
int64_t offset;
int64_t null_count;
const uint8_t* valid_bits;
} arrow_array_t;
typedef struct {
struct arrow_array_t base;
const int32_t* offsets;
const uint8_t* data;
} arrow_string_array_t;
{code}
