If an fcntl() call using F_DUPFD is successful, it actually returns the new file ID (a non-negative integer).

All error numbers used by errno are defined in <errno.h>, not <math.h>.

The discussion of abort() should note that it will call raise(SIGABRT) before exiting. Accordingly, if a SIGABRT handler was previously registered via a call to signal(), it will be executed.

fgetpos() and fsetpos() actually set errno to EIO if there is an error.

The generic-assoc-list provides a list of associations of types with expressions (and optionally a default association). If the type of the the initial expression is compatible with one of those in the generic-assoc-list, the generic selection expression evaluates to the expression specified in that association. If there is no compatible type but there is a default association, the expression specified there is used. It is an error if there is no suitable association. Only the expression from the selected association is evaluated and becomes the value of the overall generic selection expression; the initial expression and all those in other associations are not evaluated.

These are equivalent to sprintf and vsprintf, except that they take an additional argument giving the maximum number of characters to be written. If n is 0, no characters are written. Otherwise, at most n-1 characters are written based on the format string, followed by a terminating null character. They return the number of characters (not including the terminating null character) that would have been written if there was no size limit.
