The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
sock_release – close a socket Synopsis void sock_release(struct socket *sock); Arguments sock socket to close Description The socket is released from the protocol stack if it has a release callback, and the inode is then released if the socket is bound to an inode not a file. Copyright
sock_register – add a socket protocol handler Synopsis int sock_register(const struct net_proto_family *ops); Arguments ops description of protocol Description This function is called by a protocol handler that wants to advertise its address family, and have it linked into the socket interface. The value ops->family corresponds to the socket system call protocol family. Copyright
sock_poll_wait – place memory barrier behind the poll_wait call. Synopsis void sock_poll_wait(struct file *filp, wait_queue_head_t *wait_address, poll_table *p); Arguments filp file wait_address socket wait queue p poll_table Description See the comments in the wq_has_sleeper function. Copyright
sock_alloc – allocate a socket Synopsis struct socket *sock_alloc(void); Arguments void no arguments Description Allocate a new inode and socket object. The two are bound together and initialised. The socket is then returned. If we are out of inodes NULL is returned. Copyright
snprintf – Format a string and place it in a buffer Synopsis int snprintf(char *buf, size_t size, const char *fmt, …); Arguments buf The buffer to place the result into size The size of the buffer, including the trailing null space fmt The format string to use … Arguments for the format string Description The…

Return Zero if successful, or a negative error code on failure. Copyright
snd_soc_update_bits – update codec register bits Synopsis int snd_soc_update_bits(struct snd_soc_codec *codec, unsigned int reg, unsigned int mask, unsigned int value); Arguments codec audio codec reg codec register mask register mask value new value Description Writes new register value. Returns 1 for change, 0 for no change, or negative error code. Copyright
