Description

By installing the optional stdioserver.sis package from Open C deliverables, a console for debugging purposes will be created. By default, stdout will be directed to this console and stdin will also take its input from it.

It is possible to configure the redirection of these standard streams by modifying the stdioserver's config.ini file.

Solution

config.ini is installed as part of the stdioserver.sis package.

In the emulator, it is installed in \epoc32\winscw\c\system\data.
In the device, it is installed in c:\system\data.


A sample config.ini is shown below. Here, stdin input is taken from a console and stdout is redirected to a serial port. The file also contains sections for input from a file [MEDIA1] and output to a file [MEDIA4], although they are not used in this case.

 [STDIO]
 STDIN = MEDIA3
 STDOUT = MEDIA2
 
 [MEDIA1]	
 type = file
 path = C:\system\data\in.txt
 max size = 100
 
 [MEDIA2]
 type = serial
 baud = 214
 port = COMM::10
 
 [MEDIA3]
 type = console
 width = -1
 height = -1
 
 [MEDIA4]
 type = file
 path = c:\system\data\out.txt
 max size = 1000
