Detailed Description

Custom storage structure for opaque data.

Handlers for opaque types can be registered, then when a non-builtin type is encountered with a registered handler, the function pointers to unpack/pack it will be set up.

int32_t exr_attr_opaquedata_t::packed_alloc_size

If this is non-zero, the struct owns the data, if 0, is a const ref.

exr_result_t(* exr_attr_opaquedata_t::unpack_func_ptr)(exr_context_t ctxt, const void *data, int32_t attrsize, int32_t *outsize, void **outbuffer)

An application can register an attribute handler which then fills in these function pointers. This allows a user to delay the expansion of the custom type until access is desired, and similarly, to delay the packing of the data until write time.

Definition at line 398 of file openexr_attr.h.

void* exr_attr_opaquedata_t::unpacked_data

When an application wants to have custom data, they can store an unpacked form here which will be requested to be destroyed upon destruction of the attribute.
