[opensuse] [OT] arguments for execl() function

I am trying to use execl() command in order to execute 'less' program. It seems however that I need to pass to execl() the full path to less, otherwise I get an error. The path to 'less' is in PATH env variable. Is this the normal behavior of execl() ? I have this problem because I get 'less' from another env variable PAGER, but I am wondering why I need to figure out the entire path to a program in order to be able to execute it with execl(). -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
