.SH "Detailed Description"
.PP
Generic component structure\&.
Generic components structure, either statically listed by configure in static-components\&.h or dynamically loaded as a plugin\&.
.SH "Field Documentation"
.PP
.SS "unsigned hwloc_component::abi"
.PP
Component ABI version, set to HWLOC_COMPONENT_ABI\&.
.SS "void* hwloc_component::data"
.PP
Component data, pointing to a struct \fBhwloc_disc_component\fP or struct hwloc_xml_component\&.
.SS "void(* hwloc_component::finalize)(unsigned long \fBflags\fP)"
.PP
Process-wide component termination callback\&. This optional callback is called after unregistering the component from the hwloc core (before unloading the plugin)\&.
.PP
\fCflags\fP is always 0 for now\&.
.PP
\fBNote:\fP
.RS 4
If the component uses ltdl for loading its own plugins, it should load/unload them only in \fBinit()\fP and \fBfinalize()\fP, to avoid race conditions with hwloc's use of ltdl\&.
.RE
.PP
.SS "unsigned long hwloc_component::flags"
.PP
Component flags, unused for now\&.
.SS "int(* hwloc_component::init)(unsigned long \fBflags\fP)"
.PP
Process-wide component initialization callback\&. This optional callback is called when the component is registered to the hwloc core (after loading the plugin)\&.
.PP
When the component is built as a plugin, this callback should call hwloc_check_plugin_namespace() and return an negative error code on error\&.
.PP
\fCflags\fP is always 0 for now\&.
.PP
\fBReturns:\fP
.RS 4
0 on success, or a negative code on error\&.
.RE
.PP
If the component uses ltdl for loading its own plugins, it should load/unload them only in \fBinit()\fP and \fBfinalize()\fP, to avoid race conditions with hwloc's use of ltdl\&.
.SS "\fBhwloc_component_type_t\fP hwloc_component::type"
.PP
Component type\&.
