57 .Sh IMPLEMENTATION NOTES
59 In the non-threaded library
65 In the threaded library, the
67 syscall is assembled to
68 .Fn _thread_sys_getsockname
71 is implemented as a function which locks
73 for read and write, then calls
74 .Fn _thread_sys_getsockname .
80 A 0 is returned if the call succeeds, -1 if it fails.
82 The call succeeds unless:
83 .Bl -tag -width ENOTSOCKAA
87 is not a valid descriptor.
91 is a file, not a socket.
93 Insufficient resources were available in the system
94 to perform the operation.
98 parameter points to memory not in a valid part of the
99 process address space.
106 Names bound to sockets in the UNIX domain are inaccessible;
108 returns a zero length name.
