Hey all, long time since I've asked anything here, but here goes... ;)
I'm performing a character-locking sequence on my mud, where I allow
people to have a single account, with all of their characters associated
with that.
Therefore, I've modified the playerfile format, to allow for locking,
the new naming policy is:
playername.accountname
These are still located within the /player/ folder.
Now, more to my question.
When someone attempts to sign on, to allow for realtime checking, I
am doing a system() call like such:
sprintf(buf, "ls %s/%s.* > accountownz", PLAYER_DIR, lookup_name);
system(buf);
Pretty simple eh? Alright, now for the fun part.... I can check the file
(accountownz) on open for eof, however, in doing so, I lose a single
character to the check.....
(Which as far as I know in C, is required for an EOF check)
So, I guess I'm asking, anyone have any tips for checking a blank file
where I wouldn't lose that head character? (as it is essential for strcmp later
in the function)
Or is there anyway to directly get the output from the system call into a
char* or something, where I could then just parse the information within the
code itself instead of having to write it to a file?
Hope this makes sense, if not, feel free to ask away, I can explain further...
Thanks for your time reading,
