Hi,
Does anyone know how to redirect text output when issuing a system or an
execlp call? I have a GUI that insists on opening up a console whenever I
give a system function call, and I would like to redirect the text output to
a char buffer instead.

as i understand if, the first argument of execlp() is a null terminated
string containing the path of the command which to be executed.
the second argument is an array of pointers to null terminated strings,
containing the arguments to be passed to said command, ending in a null
pointer.
my question is, what does the third argument do?

nothing happens it does not call it, yet if I test the above line by substituting child with a system binary like pwd or ls it calls it without trouble. I have used the command "chmod a+x child" to make child executable but still to run child manually at the...

I'm then attempting to replace their ( the child ) process images with separate executables. I have these executables written and placed in the directory.
My problem is when I'm using execlp. When it reaches execlp in my code, it does replace the...

Hello,
I have written a program in C; this programs uses an external
proprietary library. When calling a certain function in the external
library, the particular function writes a message to stdout. I am not
particularly interested in this message, and would like to silence it
- however I do not know how to do it. (I stdout and stderr my self, so
just redirecting into oblivion is not an option).
An excerpt of the code looks like this:
