RBIMPL_ATTR_PURE() int rb_io_read_pending(rb_io_t *fptr)
Queries if the passed IO has any pending reads.
void rb_fd_set(int fd, rb_fdset_t *f)
Sets an fd to a fdset.
static int rb_fd_max(const rb_fdset_t *f)
It seems this function has no use.
static fd_set * rb_fd_ptr(const rb_fdset_t *f)
Raw pointer to fd_set.
int rb_fd_select(int nfds, rb_fdset_t *rfds, rb_fdset_t *wfds, rb_fdset_t *efds, struct timeval *timeout)
Waits for multiple file descriptors at once.
int rb_fd_isset(int fd, const rb_fdset_t *f)
Queries if the given FD is in the given set.
void rb_fd_clr(int fd, rb_fdset_t *f)
Releases a specific FD from the given fdset.
void rb_fd_init(rb_fdset_t *f)
(Re-)initialises a fdset.
void rb_fd_copy(rb_fdset_t *dst, const fd_set *src, int max)
Destructively overwrites an fdset with another.
void rb_fd_dup(rb_fdset_t *dst, const rb_fdset_t *src)
Identical to rb_fd_copy(), except it copies unlimited number of file descriptors.
void rb_fd_term(rb_fdset_t *f)
Destroys the rb_fdset_t, releasing any memory and resources it used.
void rb_fd_zero(rb_fdset_t *f)
Wipes out the current set of FDs.
Defines RBIMPL_ATTR_NONNULL.
#define RBIMPL_ATTR_NONNULL(list)
Wraps (or simulates) __attribute__((nonnull))
fd_set rb_fdset_t
The data structure which wraps the fd_set bitmap used by select(2).
#define inline
Old Visual Studio versions do not support the inline keyword, so we need to define it to be __inline.
Defines RBIMPL_ATTR_PURE.
The data structure which wraps the fd_set bitmap used by select(2).
int maxfd
Maximum allowed number of FDs.
fd_set * fdset
File descriptors buffer.
