+
+This section documents @sc{gdb/mi} commands for manipulating
+catchpoints.

+@subheading The @code{-catch-load} Command
+@findex -catch-load
+
+@subsubheading Synopsis
+
+@smallexample
+ -catch-load [ -t ] [ -d ] @var{regexp}
+@end smallexample
+
+Add a catchpoint for library load events.  If the @samp{-t} option is used,
+the catchpoint is a temporary one (@pxref{Set Breaks, ,Setting
+Breakpoints}).  If the @samp{-d} option is used, the catchpoint is created
+in a disabled state.  The @samp{regexp} argument is a regular
+expression used to match the name of the loaded library.
+
+
+@subsubheading @value{GDBN} Command
+
+The corresponding @value{GDBN} command is @samp{catch load}.
+
+@subsubheading Example
+
+@smallexample
+-catch-load -t foo.so
