Hi,
I have an app running like a daemon, that read a database and insert
mails in the qmail-queue. This daemon stop working after insert an
variable number of emails in the qmail-queue.
I have two specifics questions:
1) Is there something wrong in using this code inside an app running
like daemon? If you think so, please give me clues about the fix.
2) Is there another (better) way of put multiples (differents)
emails on the qmail queue; something like put the flat file of the
message in an special directory?
The chunk of code that insert the message is:
****************Begin of code
static char *binqqargs[2] = { "bin/qmail-queue", 0 };
static char *montab[12] = {
"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec
"
};
int send_message(char * msg, char * from, char ** recipients, int
num_recipients)
{
/* ...Adds Date:
...Adds Message-Id:*/
int r;
int wstat;
int i;
//struct tm * dt;
unsigned long msgwhen;
FILE * fdm;
FILE * fde;
pid_t pid;
int pim[2]; /*message pipe*/
int pie[2]; /*envelope pipe*/
char *sender;
/*open a pipe to qmail-queue*/
if(pipe(pim)==-1 || pipe(pie)==-1) {
return -1;
}
pid = vfork();
if(pid == -1) {
/*failure*/
return -1;
}
if(pid == 0) {
/*I am the child*/
close(pim[1]);
close(pie[1]);
/*switch the pipes to fd 0 and 1
pim[0] goes to 0 (stdin)...the message*/
if(fcntl(pim[0],F_GETFL,0) == -1) {
_exit(120);
}
close(0);
if(fcntl(pim[0],F_DUPFD,0)==-1) {
_exit(120);
}
close(pim[0]);
/*pie[0] goes to 1 (stdout)*/
if(fcntl(pie[0],F_GETFL,0) == -1) {
_exit(120);
}
close(1);
if(fcntl(pie[0],F_DUPFD,1)==-1) {
_exit(120);
}
close(pie[0]);
if(chdir(QMAIL_LOCATION) == -1) {
_exit(120);
}
execv(*binqqargs,binqqargs);
_exit(120);
}
/*I am the parent*/
fdm = fdopen(pim[1],"wb");
/*updating*/
fde = fdopen(pie[1],"wb");
if(fdm==NULL || fde==NULL) {
return -1;
}
close(pim[0]);
close(pie[0]);
/*start outputting to qmail-queue*/
fprintf(fdm,"%s\n",msg);
fclose(fdm);
/*send the envelopes*/
fprintf(fde,"F%s",from);
fwrite("",1,1,fde);
/*write a null char*/
for(i=0;i<num_recipients;i++) {
fprintf(fde,"T%s",recipients[i]);
fwrite("",1,1,fde);
/*write a null char*/
}
fwrite("",1,1,fde);
/*write a null char*/
fclose(fde);
/*wait for qmail-queue to close*/
do {
r = wait(&wstat);
} while ((r != pid) && ((r != -1) || (errno == EINTR)));
if(r != pid) {
/*failed while waiting for qmail-queue*/
return -1;
}
if(wstat & 127) {
/*failed while waiting for qmail-queue*/
return -1;
}
/*the exit code*/
if((wstat >> 8)!=0) {
/*non-zero exit status
failed while waiting for qmail-queue*/
return -1;
}
return 0;
}
****************End of code
NOTE: I took this code from the autorespond.c
