| Name: | »Line-A initialization« |
| Line-A number: | $A000 |
| Syntax: | See 'Bindings for linea_init' |
| Description: | This Line-A function serves to inquire the address of the Line-A parameter block. |
| Return value: | The function returns in d0 and a0 a pointer to the parameter
block. In a1 a pointer to a field with 3 addresses of the system fonts
will be returned, and in a2 a pointer to the start addresses of the
Line-A routines. Note: Some bindings, as that from TC, for instance, do not return the addresses to the caller, but set the parameters for the call of the Line-A functions themselves internally. |
| Availability: | All TOS versions. |
