I am writing .png file to aerospike as byte array using c code which works pretty good. While reading from aerospike data is coming as as_bytes, how to convert this as_bytes to string or pass it to my application?

To convert as_bytes to string, call as_bytes_to_string().

To pass to an application, do one of the following:

  • Pass as_bytes directly after calling as_val_reserve((as_val*)bytes).
  • Copy size and value fields using malloc() and memcpy().
  • Transfer fields using:
uint32_t s = bytes->size;
uint8_t* b = bytes->value;
bool f = bytes->free;
bytes->free = false;
