piping....
i know that I can call a program in C using the system() function...
but after i called it... how do i enter extra things into is...
example:
when i call the mail program: mail [email protected]
it asks me then for the subject...
so my question is... is there a way from my C program to send the "Subject" after i called the program with system()...
yeah,
what you can do is:
system("echo \"this is the body text\" | mail [email protected] -s \"this is the subject\"");
this will work, but you may want to use a different piping function other than system. system invokes the desired program in a shell with all its privilages. this is less efficient and secure than a function like popen.
