Functions
RegisterComponentResource TR, GLOBAL
The RegisterComponentResource function makes a component available
for use by applications (or other clients). Once the Component
Manager has registered a component, applications can find and open
the component using the standard Component Manager routines. You
provide information identifying the component and specifying its
capabilities. The Component Manager returns a component identifier
that uniquely identifies the component to the system.
UnregisterComponent ACOMPONENT
The UnregisterComponent function removes a component from the
Component ManagerO~s registration list. Most components are
registered at startup and remain registered until the computer is
shut down. However, you may want to provide some services
temporarily. In that case you dispose of the component that
provides the temporary service by using this function. Returns
zero on failure.
FindNextComponent ACOMPONENT, [COMPONENTTYPE, [COMPONENTSUBTYPE,
[COMPONENTMANUFACTURER, [COMPONENTFLAGS, [COMPONENTFLAGSMASK]]]]]
The FindNextComponent function returns the component identifier of
a component that meets the search criteria. FindNextComponent
returns a function result of 0 when there are no more matching
components.
CountComponents [COMPONENTTYPE, [COMPONENTSUBTYPE,
[COMPONENTMANUFACTURER, [COMPONENTFLAGS, [COMPONENTFLAGSMASK]]]]]
The CountComponents function returns a long integer containing the
number of components that meet the specified search criteria.
GetComponentInfo ACOMPONENT
The GetComponentInfo function returns information about the
specified component.
($type, $subtype, $manufacturer, $flags, $mask, $name, $info) =
GetComponentInfo($Component);
GetComponentListModSeed
The GetComponentListModSeed function allows you to determine if the
list of registered components has changed. This function returns
the value of the component registration seed number.
OpenComponent ACOMPONENT
The OpenComponent function allows your application to gain access
to the services provided by a component. Your application must open
a component before it can call any component functions. You specify
the component with a component identifier that your application
previously obtained from the FindNextComponent function. Returns
ComponentInstance.
CloseComponent ACOMPONENTINSTANCE
The CloseComponent function terminates your applicationO~s access
to the services provided by a component. Your application specifies
the connection to be closed with the component instance returned by
the OpenComponent() or OpenDefaultComponent() function. Returns
zero on failure.
GetComponentInstanceError ACOMPONENTINSTANCE
The GetComponentInstanceError function returns the last error
generated by a specific connection to a component. Returns zero on
failure.
ComponentFunctionImplemented CI, FTNNUMBER
The ComponentFunctionImplemented function allows you to determine
whether a component supports a specified request. Your application
can use this function to determine a componentO~s capabilities.
Returns 1 if supported.
GetComponentVersion CI
The GetComponentVersion function returns a componentO~s version
number as a coded integer.
SetDefaultComponent ACOMPONENT, FLAGS
The SetDefaultComponent function allows your component to change
the search order for registered components. You specify a component
that is to be placed at the front of the search chain, along with
control information that governs the reordering operation. The
order of the search chain influences which component the Component
Manager selects in response to an applicationO~s use of the
OpenDefaultComponent() and FindNextComponent() functions. Returns
zero on failure.
OpenDefaultComponent COMPONENTTYPE, [COMPONENTSUBTYPE]
The OpenDefaultComponent function allows your application to gain
access to the services provided by a component. Your application
must open a component before it can call any component functions.
You specify the component type and subtype values of the component
to open. The Component Manager searches for a component that meets
those criteria. If you want to exert more control over the
selection process, you can use the FindNextComponent() and
OpenComponent() functions. Returns ComponentInstance.
RegisterComponentResourceFile RESREFNUM, GLOBAL
The RegisterComponentResourceFile function registers all component
resources in the given resource file according to the flags
specified in the global parameter. Returns an integer value.
