| current-input-port | Scheme Procedure |
| scm_current_input_port () | C Function |
Return the current input port. This is the default port used
by many input procedures. Initially, current-input-port
returns the standard input in Unix and C terminology.
|
| current-output-port | Scheme Procedure |
| scm_current_output_port () | C Function |
Return the current output port. This is the default port used
by many output procedures. Initially,
current-output-port returns the standard output in
Unix and C terminology.
|
| current-error-port | Scheme Procedure |
| scm_current_error_port () | C Function |
| Return the port to which errors and warnings should be sent (the standard error in Unix and C terminology). |
| set-current-input-port port | Scheme Procedure |
| set-current-output-port port | Scheme Procedure |
| set-current-error-port port | Scheme Procedure |
| scm_set_current_input_port (port) | C Function |
| scm_set_current_output_port (port) | C Function |
| scm_set_current_error_port (port) | C Function |
Change the ports returned by current-input-port,
current-output-port and current-error-port, respectively,
so that they use the supplied port for input or output.
|
| set-current-output-port port | Scheme Procedure |
| Set the current default output port to PORT. |
| set-current-error-port port | Scheme Procedure |
| Set the current default error port to PORT. |
