Hi all,
I'd like to be able to capture the output from console after running a command.
My Googling investigations have lead me to using 'popen'.
FILE *file = popen(sqlite3 test.db .tables,r);
However, I've not been able to read the information from the returned file.
I know there are other
FILE *file = popen(sqlite3 test.db .tables,r);
However, I've not been able to read the information from the returned file.
What exactly isn't working? Maybe this helps:
NSString *fullPathToDatabase = @/Users/dave/test.db;
NSTask *sqliteTask = [[NSTask alloc] init];
NSPipe
Hi Dave,
Thanks for that, just what I was looking for.
Cheers,
Billy.

You should really use 'integerValue' rather than 'intValue' if you're otherwise
using NSIntegers. 'integerValue' will return an NSInteger (which may be 32 or
64 bits wide depending on your platform), but 'intValue' will return a C 'int'
(which is always 32 bit on the Mac and iPhone, regardless
