12 \fBcc\fR [ \fIflag\fR... ] \fIfile\fR... \fB-lsec\fR [ \fIlibrary\fR... ]
15 \fBint\fR \fBaclcheck\fR(\fBaclent_t *\fR\fIaclbufp\fR, \fBint\fR \fInentries\fR, \fBint *\fR\fIwhich\fR);
21 The \fBaclcheck()\fR function checks the validity of an \fBACL\fR pointed to by
22 \fIaclbufp.\fR The \fInentries\fR argument is the number of entries contained
23 in the buffer. The \fIwhich\fR parameter returns the index of the first entry
27 The function verifies that an \fBACL\fR pointed to by \fIaclbufp\fR is valid
28 according to the following rules:
33 There must be exactly one \fBGROUP_OBJ\fR \fBACL\fR entry.
39 There must be exactly one \fBUSER_OBJ\fR \fBACL\fR entry.
45 There must be exactly one \fBOTHER_OBJ\fR \fBACL\fR entry.
51 If there are any \fBGROUP\fR \fBACL\fR entries, then the group \fBID\fR in each
52 group \fBACL\fR entry must be unique.
58 If there are any \fBUSER\fR \fBACL\fR entries, then the user \fBID\fR in each
59 user \fBACL\fR entry must be unique.
65 If there are any \fBGROUP\fR or \fBUSER\fR \fBACL\fR entries, then there must
66 be exactly one \fBCLASS_OBJ\fR (\fBACL\fR mask) entry.
72 If there are any default \fBACL\fR entries, then the following apply:
77 There must be exactly one default \fBGROUP_OBJ\fR \fBACL\fR entry.
83 There must be exactly one default \fBOTHER_OBJ\fR \fBACL\fR entry.
89 There must be exactly one default \fBUSER_OBJ\fR \fBACL\fR entry.
95 If there are any \fBDEF_GROUP\fR entries, then the group \fBID\fR in each
96 \fBDEF_GROUP\fR \fBACL\fR entry must be unique.
102 If there are any \fBDEF_USER\fR entries, then the user \fBID\fR in each
103 \fBDEF_USER\fR \fBACL\fR entry must be unique.
109 If there are any \fBDEF_GROUP\fR or \fBDEF_USER\fR entries, then there must be
110 exactly one \fBDEF_CLASS_OBJ\fR (default \fBACL\fR mask) entry.
117 If any of the above rules are violated, then the function fails with
118 \fBerrno\fR set to \fBEINVAL\fR.
123 If the \fBACL\fR is valid, \fBalcheck()\fR will return \fB0\fR. Otherwise
124 \fBerrno\fR is set to \fBEINVAL\fR and return code is set to one of the
129 \fB\fBGRP_ERROR\fR\fR
132 There is more than one \fBGROUP_OBJ\fR or \fBDEF_GROUP_OBJ\fR \fBACL\fR entry.
138 \fB\fBUSER_ERROR\fR\fR
141 There is more than one \fBUSER_OBJ\fR or \fBDEF_USER_OBJ\fR \fBACL\fR entry.
147 \fB\fBCLASS_ERROR\fR\fR
150 There is more than one \fBCLASS_OBJ\fR (\fBACL\fR mask) or \fBDEF_CLASS_OBJ\fR
151 (default \fBACL\fR mask) entry.
157 \fB\fBOTHER_ERROR\fR\fR
160 There is more than one \fBOTHER_OBJ\fR or \fBDEF_OTHER_OBJ\fR \fBACL\fR entry.
166 \fB\fBDUPLICATE_ERROR\fR\fR
169 Duplicate entries of \fBUSER\fR, \fBGROUP\fR, \fBDEF_USER\fR, or
176 \fB\fBENTRY_ERROR\fR\fR
179 The entry type is invalid.
185 \fB\fBMISS_ERROR\fR\fR
188 Missing an entry. The \fIwhich\fR parameter returns \fB\(mi1\fR in this case.
194 \fB\fBMEM_ERROR\fR\fR
197 The system cannot allocate any memory. The \fBwhich\fR parameter returns
198 \fB\(mi1\fR in this case.
