__get_fd_flags

Syntax

#include <libc/fd_props.h> unsigned long __get_fd_flags(int fd);

Description

This internal functions gets the flags associated with file descriptor fd, if any. The flags are some properties that may be associated with a file descriptor (see section __set_fd_properties).

This function will return zero, if no flags are associated with fd. The caller should first check that there are flags associated with fd using __has_fd_properties (see section __has_fd_properties), before calling __get_fd_flags. This will allow the cases of no flags and the flags being zero to be distinguished.

Return Value

The flags, if any; otherwise zero.
