  53 .SH DESCRIPTION
  54 .sp
  55 .LP
  56 The \fBgetexecattr()\fR function returns a single \fBexec_attr\fR(4) entry.
  57 Entries can come from any of the sources specified in the
  58 \fBnsswitch.conf\fR(4) file.
  59 .sp
  60 .LP
  61 Successive calls to \fBgetexecattr()\fR return either successive
  62 \fBexec_attr\fR entries or \fINULL\fR. Because \fBgetexecattr()\fR always
  63 returns a single entry, the \fBnext\fR pointer in the  \fBexecattr_t\fR data
  64 structure points to \fINULL\fR.
  65 .sp
  66 .LP
  67 The internal representation of an \fBexec_attr\fR entry is an \fBexecattr_t\fR
  68 structure defined in  <\fBexec_attr.h\fR> with the following members:
  69 .sp
  70 .in +2
  71 .nf
  72 char              *name;   /* name of the profile */
  73 char              *type;   /* type of profile */
  74 char              *policy; /* policy under which the attributes are */
  75                            /* relevant*/

  76 char              *res1;   /* reserved for future use */
  77 char              *res2;   /* reserved for future use */
  78 char              *id;     /* unique identifier */
  79 kva_t             *attr;   /* attributes */

  86 The \fBfree_execattr()\fR function releases memory. It follows the \fBnext\fR
  87 pointers in the \fBexecattr_t\fR structure so that the entire linked list is
  88 released.
  89 .sp
  90 .LP
  91 The \fBsetexecattr()\fR function "rewinds" to the beginning of the enumeration
  92 of \fBexec_attr\fR entries. Calls to \fBgetexecuser()\fR can leave the
  93 enumeration in an indeterminate state. Therefore, \fBsetexecattr()\fR should be
  94 called before the first call to \fBgetexecattr()\fR.
  95 .sp


 121 arguments are logically AND-ed together so that only entries exactly matching
 122 all of the arguments are returned. Wildcard matching applies if there is no
 123 exact match for an \fBID\fR. Any argument can be assigned the \fINULL\fR value
 124 to indicate that it is not used as part of the matching criteria. The \fB\fR
 125 search_flag controls whether the function returns the first match
 126 (\fBGET_ONE\fR), setting the \fBnext\fR pointer to \fINULL\fR or all matching
 127 entries (\fBGET_ALL\fR), using the \fBnext\fR pointer to create a linked list
 128 of all entries that meet the search criteria. See  \fBEXAMPLES\fR.
 129 .sp
 130 .LP
 131 Once a list of entries is returned by \fBgetexecuser()\fR or
 132 \fBgetexecprof()\fR, the convenience function \fBmatch_execattr()\fR can be
 133 used to identify an individual entry. It returns a pointer to the individual
 134 element with the same profile name (\fIprofname\fR), type name (\fItype\fR),
 135 and \fIid\fR. Function parameters set to \fINULL\fR are not used as part of the
 136 matching criteria. In the event that multiple entries meet the matching
 137 criteria, only a pointer to the first entry is returned. The
 138 \fBkva_match\fR(3SECDB) function can be used to look up a key in a key-value
 139 array.
 140 .SH RETURN VALUES
 141 .sp
 142 .LP
 143 Those functions returning data only return data related to the active policy.
 144 The \fBgetexecattr()\fR function returns a pointer to a  \fBexecattr_t\fR if it
 145 successfully enumerates an entry; otherwise it returns \fINULL\fR, indicating
 146 the end of the enumeration.
 147 .SH USAGE
 148 .sp
 149 .LP
 150 The \fBgetexecattr()\fR, \fBgetexecuser()\fR, and \fBgetexecprof()\fR functions
 151 all allocate memory for the pointers they return. This memory should be
 152 deallocated with the \fBfree_execattr()\fR call. The \fBmatch_execattr()\fR
 153 function does not allocate any memory. Therefore, pointers returned by this
 154 function should not be deallocated.
 155 .sp
 156 .LP
 157 Individual attributes may be referenced in the \fBattr\fR structure by calling
 158 the \fBkva_match\fR(3SECDB) function.
