dlite-bson

Built-in support for BSON representation of instances.

Functions

int dlite_bson_append_instance(unsigned char *buf, int bufsize, const DLiteInstance *inst)

Append instance to BSON document.

Arguments:

• buf: Pointer to a BSON document to append data to. The memory pointed to must have been initialised with bson_init_document().

• bufsize: Size of memory segment pointed to by buf. No more than bufsize bytes will be written.

• inst: DLite instance to append to BSON document.

Returns: Number of bytes appended (or would have been appended) to buf. A negative error code is returned on error.

unsigned char *dlite_bson_from_instance(const DLiteInstance *inst, size_t *size)

Serialise instance to BSON and return a pointer to a newly allocated memory region with the BSON content.

If size is not NULL, it is assigned to the length of the BSON content.

Returns NULL on error.

DLiteInstance *dlite_bson_load_instance(const unsigned char *doc)

Create a new instance from bson document and return it.

Returns NULL on error.
