42 This function allocates and initializes a capability state in working
44 It then sets the contents of this newly created capability state to the
45 state represented by the human-readable, null terminated character string
49 This function may cause memory to be allocated.
50 The caller should free any releasable memory, when the capability state in
51 working storage is no longer required, by calling
56 .Sh IMPLEMENTATION NOTES
57 FreeBSD's support for POSIX.1e interfaces and features is still under
58 development at this time.
60 Upon successful completion, the function returns a pointer to the
61 internal representation of the capability in working storage.
66 is set to indicate the error.
68 If any of the following conditions occur, the
70 function shall return a value of
74 to the corresponding value:
79 argument does not refer to a character string, the string pointed to by
81 is not parseable by the function, the text string contains a
82 capability name or a flag character that the implementation does not
85 The capability state to be returned requires more memory than is allowed
86 by the hardware or system-imposed memory management constraints.
96 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
97 of the draft continues on the cross-platform POSIX.1e implementation
98 mailing list. To join this list, see the
100 POSIX.1e implementation
101 page for more information.
103 POSIX.1e support was introduced in
105 and development continues.
