I am trying to port the Beta test version of MicroEmacs to Microport
System V/AT version 2.4 (286 version). Understandably there are going to
be some problems, that's why Beta tests exist. I have had experience
only with Microport UNIX and am experiencing problems with the
conversion.
First off, there is the following chunk of code:
fd_set fdset;
struct timeval timeout;
char cseq[6]; /* current sequence being parsed */
c = tgetc();
/* if it is not an escape character */
if (c != 27) {
/* flag control chars as such */
if (c>=0x00 && c<=0x1F)
c = CTRL | (c+'@');
return(c);
}
/* process a possible escape sequence */
/* set up to check the keyboard for input */
fdset.fds_bits[0] = (fd_mask)1;
timeout.tv_sec = 0;
timeout.tv_usec = 35000L;
/* check to see if things are pending soon */
if (kbdmode != PLAY && select(1, &fdset, NULL, NULL, &timeout) == 0)
return(CTRL | '[');
/* a key is pending within 1/30 of a sec... its an escape sequence */
This seems to be a sort of time pending check on input based on the
stuctures timeout and fdset, and the system call select. ( select I
understand to be a BSD animal )
Could someone suggest a System V equivalent function to select, or
possibly a function which could perform the same as above?
I am also experiencing core dumps, ( if I circumvent the above code
section. ). I have traced them down to a call to tcapopen, which calls
tgetstr and then makes a call to a routine 'lp' to which I can find no
reference to. It sounds like curses may be getting upset about some
termcap equivalent calls, sending function references into never-never
land. Tcapopen is in tcap.c.
As a point of reference, is anyone else porting Micro-Emacs 3.10 Beta to
Microport System V/AT 2.4? If so please write me with some suggestions
on my project.
I am using this as a training ground for UNIX and C. Any guidance is
greatly appreciated.
Please e-mail your responses to me. I will forward any success summaries to
Daniel Lawrence and summarize for the net.
BTW this is a modified reposting of an article I tried to send last
week. I hope this one gets further.....
Thanks in advance....
