best way to construct and send email in c

[rotis23]

hi there,

what is the best way to construct and send an email in c.

i don't want to have to call a bash shell script that uses the mail command.

TIA,

You can write a C program that
1) reads data from the user and writes it to a file. You write the C code or just fork and exec 'vi'.
2) exec the mail command ,redirecting the input from the file written in (1)


otherwise you can directly exec the mail command and compose the mail over there itself.


Writing a complete mailer application is a much more complex task.

thanks,

that was what i was thinking of doing. i wasn't sure weather ansi c had a similar command.

does anyone know how to send a pager message in c. it seems the best way, like the email problem, is to call the snpp command using exec.

any other ideas?

solution (linux):

email - use execl command to call linux mail command

pager - use execl command to call linux snpp command

sorted!

if you will do it in 'C', try
--------------------------------------------
#include <stdio.h>
#include <unistd.h>
#include <sys/wait.h>

#define NOFILE 64

/*********
change the next 2 lines
*********/

#define SUBJECT &quot;Mail-Subject&quot;
#define MAILTO &quot;username@domain.com&quot;

int main(int argc,char **argv)
{
extern char *basename(char *);
char *myname = basename(*argv);
int ppp[2], mail;

if(0 >pipe(ppp)) exit(fprintf(stderr,&quot;%s: Can't create pipe\n&quot;,myname));

if(0 >(mail = fork())) exit(fprintf(stderr,&quot;%s: Can't fork\n&quot;,myname));
if(!mail){ /* child process, start mail */
(void)dup2(ppp[0],0);

for(mail = 3; mail< NOFILE; (void)close(mail++));

execl(&quot;/bin/mailx&quot;,&quot;mailx&quot;,&quot;-s&quot;,SUBJECT,MAILTO,(char *)0);

exit(fprintf(stderr,&quot;%s: Can't execl\n&quot;,myname));
}

/* father-process, write text for mail */

(void)dup2(ppp[1],1);

fprintf(stdout,&quot;...........mail text............\n&quot;
fprintf(stdout,&quot;................................\n&quot;
fprintf(stdout,&quot;................................\n&quot;
fprintf(stdout,&quot;................................\n&quot;
fprintf(stdout,&quot;...........end mail.............\n&quot;

fflush(stdout);
(void)close(1);
(void)close(ppp[0]);
(void)close(ppp[1]);
(void)wait(&mail);
exit(0);
}
