Is there another layer hidden behind for printing with putchar() in the if-condition?
The return value is EOF or a single vowel, which is the first part bugging me.
Does that mean in if (putchar(c) == EOF || putchar(c) == EOF) , function putchar(c) gets actually executed twice?
I thought this line is just a condition, and before the end only the else block is executed so that the value is 'e', without printing.
Let me put my question in another way:
Is there another layer for printing hidden behind, such as when 'e' is encountered in 'Test'?
Is this correct?
Thanks!

Solution: A horrible solution could be to check for that flag everytime I have to read a field in the... (11 Replies)

I wonder, how the syntaxes "f()" and "(*f)()" are treated as same without any error? Is this an improvement or ANSI/ISO... (1 Reply)

pure-quotacheck refuses to scan directories with uid = 0 (root) or gid = 0 (wheel/root) .
pure-quotacheck performs a chroot() call to the home directory. It never traverses parent directories.
pure-quotacheck only scans real files (no socket, no pipe, etc) .
pure-quotacheck enforces read access on directories to prevent against people doing chmod 0 before a quota scan.
pure-quotacheck enforces write access on the home directory to properly write the .ftpquota file.
pure-quotacheck never scans the same inode/device pair twice.
