## Function Documentation

## ◆ embryo_data_string_length_get()

EAPI int embryo_data_string_length_get | ( | Embryo_Program * | ep,
|  | Embryo_Cell * | str_cell
| ) |  |

Retrieves the length of the string starting at the given cell.

Parameters

  ep | The program the cell is part of.
  str_cell | Pointer to the first cell of the string.

Returns
  The length of the string. `0` is returned if there is an error.

## ◆ embryo_data_string_get()

EAPI void embryo_data_string_get | ( | Embryo_Program * | ep,
|  | Embryo_Cell * | str_cell,
|  | char * | dst
| ) |  |

Copies the string starting at the given cell to the given buffer.

Parameters

  ep | The program the cell is part of.
  str_cell | Pointer to the first cell of the string.
  dst | The given buffer.

## ◆ embryo_data_string_set()

EAPI void embryo_data_string_set | ( | Embryo_Program * | ep,
|  | const char * | src,
|  | Embryo_Cell * | str_cell
| ) |  |

Copies string in the given buffer into the virtual machine memory starting at the given cell.

Parameters

  ep | The program the cell is part of.
  src | The given buffer.
  str_cell | Pointer to the first cell to copy the string to.

## ◆ embryo_data_address_get()

EAPI Embryo_Cell * embryo_data_address_get | ( | Embryo_Program * | ep,
|  | Embryo_Cell | addr
| ) |  |

Retreives a pointer to the address in the virtual machine given by the given cell.

Parameters

  ep | The program whose virtual machine address is being queried.
  addr | The given cell.

Returns
  A pointer to the cell at the given address.
