Archived:Redirecting stdin and stdout streams in Open C
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.
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
