- Look up the hash of the hook installed on hook account at position
- Write the 32 byte hash to
int64_t hook_hash ( uint32_t write_ptr, uint32_t write_len, int32_t hook_no );
uint8_t hash; int64_t bytes_written = hook_hash(hash, 32, -1);
|write_ptr||uint32_t||Pointer to a buffer of a suitable size to store the output. Should be at least 32 bytes.|
|write_len||uint32_t||Length of the output buffer.|
|hook_no||int32_t||The position in the hook chain the hook is located at, or -1 for the currently executing hook.|
|int64_t||The number of bytes written|
If negative, an error:
- pointers/lengths specified outside of hook memory.
- The specified hook sequence number doesn't exist in the hook chain.
