Data Structures
struct	sigset_t
	Set of signals (bitmask). More...

struct	timespec
	Time value with nanosecond resolution. More...

struct	timeval
	Time value with microsecond resolution. More...

Macros
#define	FD_SETSIZE ZVFS_FD_SETSIZE
	Maximum number of file descriptors in an fd_set.

#define	SIGRTMIN (CONFIG_THREAD_CANCEL_SIGNAL_NUMBER + 2)

#define	SIGRTMAX SIGRTMIN

Typedefs
typedef long	suseconds_t
	Microsecond time component type.

typedef struct zvfs_fd_set	fd_set
	Set of file descriptors for select()/pselect().

Functions
int	pselect (int nfds, fd_set readfds, fd_set writefds, fd_set exceptfds, const struct timespec timeout, const sigset_t *sigmask)
	Synchronous multiplexed I/O with signal-mask and nanosecond timeout.

int	select (int nfds, fd_set readfds, fd_set writefds, fd_set errorfds, struct timeval timeout)
	Synchronous multiplexed I/O (legacy interface, use pselect() for new code).

void	FD_CLR (int fd, fd_set *fdset)
	Remove a file descriptor from an fd_set.

int	FD_ISSET (int fd, fd_set *fdset)
	Test whether a file descriptor is in an fd_set.

void	FD_SET (int fd, fd_set *fdset)
	Add a file descriptor to an fd_set.

void	FD_ZERO (fd_set *fdset)
	Clear all file descriptors from an fd_set.
