_CP_get is equivalent to the following BASIC statement:
get result, expression1 setting expression2 from expression3 until string1 returning string2, waiting expression4
int _CP_get(int type, CPSTR** result, int expression1, int expression2, int expression3, CPSTR* string1, CPSTR** string2, int expression4)
The type parameter is a bit mask that can be used to set various options:
| _CP_GET_X | The getx form of get. |
| _CP_GET_LEN | A desired length is present. |
| _CP_GET_SET | A setting parameter is present. |
| _CP_GET_UNTIL | An until parameter is present. |
| _CP_GET_RTN | A returning parameter is present. |
| _CP_GET_WAIT | A waiting parameter is present. |
| _CP_GET_THEN_ELSE | Then/Else condition. |
| _CP_GET_ELSE | Else only condition. |
This function returns -1 if an error occurs. The error code is contained in _CP_errno.
