PROLOG<\/a> This manual page is part of the POSIX Programmer\u2019s Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.<\/p>\n sys\/un.h \u2014 definitions for UNIX domain sockets<\/p>\n #include The sa_family_t sun_family Address family. The sockaddr_un<\/b> structure is used to store addresses for UNIX domain sockets. Pointers to this type shall be cast by applications to struct sockaddr *<\/b> for use with socket functions.<\/p>\n The The following sections are informative.<\/i><\/p>\n The size of sun_path<\/i> 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.<\/p>\n Applications should not assume a particular length for sun_path<\/i> or assume that it can hold {_POSIX_PATH_MAX} bytes (256).<\/p>\n Although applications are required to initialize all members (including any non-standard ones) of a sockaddr_in6<\/b> structure (see None.<\/p>\n None.<\/p>\n
