Hi there,

i am trying to get the username , ttyp ,ip address and/or name into a c program on sco openserver 5.0.5

i tried utmp which gives me the username and ttyp, but i cant get the others, it doesnt seem to support ut_addr??

SO... i thought id pipe who -mxu from the command line
ie ./myprog | who -mxu

and use that. but how do i read stdin, anyone have an example of doing this??

cheers

You've got your pipe backwards. The way it's written, you're feeding stdout of your program to stdin of who.

As for reading stdin, you would do that the same way you read user input, i.e. use the cin input stream or gets()

its been a long night, yep, it works if you pipe the right way!!
