Hi friends,
i have a doubt... can i redirect the output printed on the console to a variable in C program ?? (Eg: say i am using linux OS coding in C and inside the C code i have used system("date") which prints the date to the console !!! and now if i want the next statement in the C code to have this date's output in a charecter array... is this possible ????)sorry if i am talking something nonsense.. hahah...
Use popen() to treat the input (or output) of other processes as FILE* handles (fgets, fprintf etc compatible)
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
thanks a lot for reply salem.....
but really i didnt get what u are saying.... sorry...
can u plese be more detail...
see if this page helps: http://tldp.org/LDP/lpg/node12.html
Normally, when people say use the foo() function, your first reaction should be go read about it in the manual page, say
man popen
rather than saying "huh" every time someone uses a new function you've never heard of. We're not here to regurgitate every single manual page in small morcels for every single noob that wanders by.

i really agree with what u are saying...and i have not even asked to give the ready code for something...the first thing what i did was man popen.. really... but since i am a beginner in C and linux... had some problem in understanding and how to extract the info using the return value of the file pointer it returns....so i asked u to explain it a bit....Originally Posted by Salem

You don't know how to read from a file? Don't you have a C book? Don't you know how to read a FAQ? Don't you know how to search the internet? It returns a file pointer. Use functions that read from file pointers. Pretty simple stuff.
Quzah.
Hope is the first step on the road to disappointment.
I should have figured that would have been the response from the profusion of punctuation, and the "skiddie" speak.

Thanks all for suggestions..
