56 support for POSIX.1e interfaces and features is still under
57 development at this time.
59 Upon successful completion, the function shall return a value of zero.
60 Otherwise, a value of -1 shall be returned and
62 set to indicate the error.
64 If any of the following conditions occur, the
66 function shall return -1 and set
68 to the corresponding value:
71 At least one of the values of the
77 arguments does not refer to the corresponding entity.
84 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
85 of the draft continues on the cross-platform POSIX.1e implementation
86 mailing list. To join this list, see the
88 POSIX.1e implementation
89 page for more information.
91 Support for POSIX.1e Capabilities was developed as part of the TrustedBSD
93 POSIX.1e Capability support was introduced in
95 and development continues.
