@section Commands to Set Tracepoints
Before running such a @dfn{trace experiment}, an arbitrary number of
tracepoints can be set. Like a breakpoint (@pxref{Set Breaks}), a
tracepoint has a number assigned to it by @value{GDBN}. Like with
breakpoints, tracepoint numbers are successive integers starting from
one. Many of the commands associated with tracepoints take the
tracepoint number as their argument, to identify which tracepoint to
work on.
tracepoints can be set. A tracepoint is actually a special type of
breakpoint (@pxref{Set Breaks}), so you can manipulate it using
standard breakpoint commands. For instance, as with breakpoints,
tracepoint numbers are successive integers starting from one, and many

as their argument, to identify which tracepoint to work on.

commands to examine the values these data had at the time the
tracepoint was hit.
Tracepoints do not support every breakpoint feature. Conditional
expressions and ignore counts on tracepoints have no effect, and
tracepoints cannot run @value{GDBN} commands when they are
hit. Tracepoints may not be thread-specific either.

The @code{trace} command is very similar to the @code{break} command.
Its argument can be a source line, a function name, or an address in
the target program. @xref{Set Breaks}. The @code{trace} command
defines a tracepoint, which is a point in the target program where the
debugger will briefly stop, collect some data, and then allow the
program to continue. Setting a tracepoint or changing its commands
doesn't take effect until the next @code{tstart} command; thus, you
cannot change the tracepoint attributes once a trace experiment is
running.
