NAME¶
XrmEnumerateDatabase - enumerate resource database entries
SYNTAX¶
#include <X11/Xresource.h>

XrmEnumAllLevels |
0 |
#define |
XrmEnumOneLevel |

Bool XrmEnumerateDatabase(XrmDatabase database,
XrmNameList name_prefix, XrmClassList class_prefix, int
mode, Bool (* proc)(), XPointer arg);
ARGUMENTS¶
- database
- Specifies the resource database.
- name_prefix
- Specifies the resource name prefix.
- class_prefix
- Specifies the resource class prefix.
- mode
- Specifies the number of levels to enumerate.
- proc
- Specifies the procedure that is to be called for each matching entry.
- arg
- Specifies the user-supplied argument that will be passed to the
procedure.
DESCRIPTION¶
The
XrmEnumerateDatabase function calls the specified procedure for each
resource in the database that would match some completion of the given
name/class resource prefix. The order in which resources are found is
implementation-dependent. If mode is
XrmEnumOneLevel, a resource must
match the given name/class prefix with just a single name and class appended.
If mode is
XrmEnumAllLevels, the resource must match the given
name/class prefix with one or more names and classes appended. If the
procedure returns
True, the enumeration terminates and the function
returns
True. If the procedure always returns
False, all
matching resources are enumerated and the function returns
False.
The procedure is called with the following arguments:
(* proc)(database, bindings, quarks, type, value, arg)
XrmDatabase * database;
XrmBindingList bindings;
XrmQuarkList quarks;
XrmRepresentation * type;
XrmValue * value;
XPointer arg;
The bindings and quarks lists are terminated by
NULLQUARK. Note that
pointers to the database and type are passed, but these values should not be
modified.
The procedure must not modify the database. If Xlib has been initialized for
threads, the procedure is called with the database locked and the result of a
call by the procedure to any Xlib function using the same database is not
defined.
