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.

EAPI int embryo_data_string_length_get ( Embryo_Program *  ep,
