Dear Sir,

the actual application is like that i need to fetch the data from database and send it to portal via this system(/etc/ppp/dailout &) .

if i call database opening command and fetch the datavalues and store them in variable then i close the database by calling "close_sqlite3" command .
still I am not able to call fork () and create child process for the execution of system....command

The error always i receive is by calling perror("system");
system:No child process.
