_CP_readt is equivalent to the readt BASIC statement.
Which flavor of readt is dependent upon the command type:
| Type | BASIC Statement |
|---|---|
| _CP_READT_ELSE | readt result else * return -1 |
| _CP_READT_L_ELSE | readtl result else * return -1 |
| _CP_READTX_ELSE | readtx result else * return -1 |
| _CP_READT_ONERR | readt result onerr * return -1 |
| _CP_READT_L_ONERR | readtl result onerr * return -1 |
| _CP_READTX_ONERR | readtx result onerr * return -1 |
int _CP_readt(int type, CPSTR** result)
This function returns -1 if an error occurs. The error code is contained in _CP_errno. PE_TAPE indicates a tape error.
/* Prints the next tape block. */ CPSTR * xx = _CP_str_null; _CP_readt(_CP_READT_ELSE, xx); _CP_print(xx);
