| Name: | »Print screen dump« - Hardcopy print-out
|
| Opcode: | 36
|
| Syntax: | int16_t Prtblk( PBDEF *par );
|
| Description: | The XBIOS routine Prtblk prints out a given segment of the
memory. The pointer par serves to describe the structure of
the screen build-up.
The print process can be terminated with the key combination Alternate/Help. Note: Before calling this function the system variable prt_cnt should be set to 1 to make anything at all happen. After return of the function the variable should be set back to -1. Warning: As of MagiC 3, this function is only present as a dummy routine; possibly the desired functionality may be restored by an external program. |
| Return value: | The function returns 0 if the printout was successful,
otherwise a non-zero value.

| Name: | »Screen dump« - Print out the screen contents.
|
| Opcode: | 20
|
| Syntax: | void Scrdmp( void );
|
| Description: | The XBIOS routine Scrdmp prints out the contents of the screen
as hardcopy.
The print process can be terminated with the key combination Alternate/Help. Note: The function jumps via the scr_dump system vector, and unfortunately does not work with all available printers. Warning: As of MagiC 3, this function is only present as a dummy routine; possibly the desired functionality may be restored by an external program. |
| Return value: | The function does not return a result.

| Syntax: | int16_t Setprt( int16_t config );
| ||||||||||||||
| Description: | The XBIOS routine Setprt sets or reads the current settings of
the printer. The following bits can be specified in the parameter
config:
With config = -1 the current configuration will be returned. All further bits are reserved for future use. Note: Unfortunately, the settings made by this function will be ignored by almost all parts of the operating system. So in one's own programs one ought to evaluate at least the choice of port as well as the type of paper. | ||||||||||||||
| Return value: | The function returns the old configuration.
