CONNECTAT(2) FreeBSD System Calls Manual CONNECTAT(2) NAME connectat -- initiate a connection on a socket LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <sys/types.h> #include <sys/socket.h> #include <fcntl.h> int connectat(int fd, int s, const struct sockaddr *name, socklen_t namelen); DESCRIPTION The connectat() system call initiates a connection on a socket. It works just like the connect(2) system call with two exceptions: 1. It is limited to sockets in the PF_LOCAL domain. 2. If the file path stored in the sun_path field of the sock- addr_un structure is a relative path, it is located relative to the directory associated with the file descriptor fd. If connectat() is passed the special value AT_FDCWD in the fd parameter, the current working directory is used and the behavior is identical to a call to connect(2). RETURN VALUES The connectat() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error. ERRORS The connectat() system call may fail with the same errors as the connect(2) system call for a UNIX domain socket or with the following errors: [EBADF] The sun_path field does not specify an absolute path and the fd argument is neither AT_FDCWD nor a valid file descriptor. [ENOTDIR] The sun_path field is not an absolute path and fd is neither AT_FDCWD nor a file descriptor associated with a directory. SEE ALSO bindat(2), connect(2), socket(2), unix(4) AUTHORS The connectat was developed by Pawel Jakub Dawidek <pawel@dawidek.net> under sponsorship from the FreeBSD Foundation.
