What would I use in place of select()
I'm modifying some code so that there is a timer on in. When the system has select(), I can just place a timer on select. However, what are some alternatives in the noselect case? Here is a code snippet to give you some idea,
Code:
/*Here is the section that has a timer*/
#ifndef NOSELECT
/* Set up the input file set for the select call */
FD_ZERO(&input_set);
FD_SET(0,&input_set);
FD_SET(rst,&input_set);
struct timeval tv;
tv.tv_sec = atoi(opt[OPT_IDLEOUT].str)*60;
tv.tv_usec = 0;
#endif
/*What are some ideas that I could do this case?*/
#ifdef NOSELECT
/* Copy text while I can -- otherwise go to input mode */
if (output())
{ /*}*/
/* Wait four seconds for a command */
alarm(4);
if (!setjump(jenv,1))
{
read(0,&ch,1); /* Alarm busts us out of here */
alarm(0);
docmd(ch);
lastaction= time((time_t *)0);
}
#else
/* Wait for input in file or from user */
iset= input_set;
select(rst+1, &iset, NULL, NULL, &tv);/* process typed command from user */
if (FD_ISSET(0,&iset))
{
read(0,&ch,1);
docmd(ch);
lastaction= time((time_t *)0);
}
/* process new text in file */
if (FD_ISSET(rst,&iset))
{
while (!output())
;
#endif /*NOSELECT*/
