- Serialize the object currently occupying the specified slot
- Write the serialized version of the object to the output buffer
For small objects you may avoid using a buffer. Specify
write_ptr, write_lento attempt to return the slotted object as big endian packed data in the
int64_treturn code. Up to 63 bits of data may be returned this way.
int64_t slot ( uint32_t write_ptr, uint32_t write_len, uint32_t slot_no );
uint8_t txn; int64_t bytes_written = slot(txn, 512, 1); // assumes a transaction is slotted into slot=1
|write_ptr||uint32_t||Pointer to a buffer of a suitable size to store the output.|
|write_len||uint32_t||Length of the output buffer.|
|slot_no||uint32_t||The slot number|
|int64_t||The number of bytes written|
If negative, an error:
- pointers/lengths specified outside of hook memory.
- output buffer was not large enough to hold the serialized object
