.SH "DESCRIPTION"
Basic searching function locating elements of the VOBJECT by qualified
name. The function is a varargs function (like sprintf) and the list
of arguments must be NULL terminated (hence the appearance of the
p_qualifier argument in the arglist). Valid calls might be:
vf_get_property(&p_out, p_object, VFGP_FIND, NULL, "N", NULL);
.br
- Find and return "N" properties. If there are none, return FALSE.
Vf_get_property(&p_out, p_object, VFGP_FIND, NULL, "TEL", "WORK", NULL);
.br
- Find and return "TEL" entries qualified by the "work" attribute
(ie. Work phone numbers). If there are none, return FALSE.
Vf_get_property(&p_out, p_object, VFGP_GET, NULL, "TEL", "WORK", NULL);
.br
- Find and return work phone number. The entry is automatically
added if not pre-existing.
Vf_get_property(&p_out, p_object, VFGP_GET, NULL, "TEL", "WORK", NULL);
.br
- Find and return work phone numbers in the group identifier by the "ME"
identifier. The entry is automatically added if not pre-existing.
Vf_get_property(&p_out, p_object, VFGP_FIND, "ME", "*", NULL);
.br
- Effectively enumerates all entries in the "ME" group.
A pointer to the first property matching the search criteria is returned
via the pp_prop argument. The search actually locates all such matches
and pointer to subsequent entries (if there are >1) may be found by
calling the vf_get_next_property() function.
The tags may occur in any order _except_ that the p_name must be first.
Note that the VF_PROP_T returned by pp_prop is an opaque type and the
functions vf_get_prop_xxxx() etc. Must be used to locate real "values".
Cached search results (the list enumerated by subsequent calls to the
vf_get_next_property() function) are maintained through the use of a
a single internal pointer therefore this method is not thread safe.
.SH "RETURNS"
TRUE iff found/added successfully. Ptr to prop returned via pp_prop.
