socketcall(2)                 System Calls Manual                socketcall(2)

JMENO
       socketcall - socketove systemove volani

KNIHOVNA
       Standardni knihovna C (libc, -lc)

POUZITI
       #include <linux/net.h>        /* Definition of SYS_* constants */
       #include <sys/syscall.h>      /* Definition of SYS_socketcall */
       #include <unistd.h>

       int syscall(SYS_socketcall, int call, unsigned long *args);

       Note: glibc provides no wrapper for socketcall(), necessitating the use
       of syscall(2).

POPIS
       socketcall() je bezny vstupni bod jadra pro socketove systemove volani.
       call urcuje, ktera socketova funkce bude vyvolana.  args jsou ukazatele
       do bloku obsahujiciho aktualni parametry, ktere jsou predany
       prislusnemu volani.

       Uzivatelske programy by mely volat prislusne funkce jejich obvyklymi
       jmeny.  Funkci socketcall() by meli pouzivat jen implementatori
       standardnich knihoven a hackeri zabyvajici se podrobne jadrem Linuxu.

VERZE
       On some architectures--for example, x86-64 and ARM--there is no
       socketcall()  system call; instead socket(2), accept(2), bind(2), and
       so on really are implemented as separate system calls.

STANDARDY
       Linux.

       On x86-32, socketcall()  was historically the only entry point for the
       sockets API.  However, starting in Linux 4.3, direct system calls are
       provided on x86-32 for the sockets API.  This facilitates the creation
       of seccomp(2)  filters that filter sockets system calls (for new
       user-space binaries that are compiled to use the new entry points)  and
       also provides a (very) small performance improvement.
