sys/un.h - definitions for UNIX domain sockets
Návod, kniha: POSIX Programmer's Manual
#include <sys/un.h>
The
<sys/un.h> header shall define the
sockaddr_un structure
that includes at least the following members:
sa_family_t sun_family Address family.
char sun_path[] Socket pathname.
The
sockaddr_un structure is used to store addresses for UNIX domain
sockets. Values of this type shall be cast by applications to
struct
sockaddr for use with socket functions.
The
sa_family_t type shall be defined as described in
<sys/socket.h> .
The following sections are informative.
The size of
sun_path has intentionally been left undefined. This is
because different implementations use different sizes. For example, 4.3 BSD
uses a size of 108, and 4.4 BSD uses a size of 104. Since most implementations
originate from BSD versions, the size is typically in the range 92 to 108.
Applications should not assume a particular length for
sun_path or assume
that it can hold {_POSIX_PATH_MAX} characters (255).
None.
