Im having trouble executing a system command and having it pass the text to a variable, anyone have any idea how to do it?
Whenever i try i get "Invalid Initializer"
help would be appreciated - thanks
edit:
Something like
system("uname -r") /*returns the hostname*/
and setting a variable as that instead of having to call system("uname -r") every time.
Distribution: Normally Caldera 3.2, but currently WinXP only

Well - of course it happens like that, cause system() returns zero on success and thatfore you receive the zero-character '\0' into your host-variable. If (what is definately not the case) uname returned the host, the returnvalue would be c-string (a pointer to the first char of the string) and therefore you'd have needed a char*. Actually, uname prints any output to STDOUT which here is the console.
You can force the output to be written in a textfile and then read it's content into the variable. Here is an yet untested example:
Think, that might be more useful. And: it's portable
Sorry about not including the headers, but I do not exactly know which ones to include. But there are sources...
