Disabling breakpoints

Rather than deleting a breakpoint, watchpoint, or catchpoint, you might
prefer to "disable" it.  This makes the breakpoint inoperative as if it
had been deleted, but remembers the information on the breakpoint so
that you can "enable" it again later.
   You disable and enable breakpoints, watchpoints, and catchpoints with
the `enable' and `disable' commands, optionally specifying one or more
breakpoint numbers as arguments.  Use `info break' or `info watch' to
print a list of breakpoints, watchpoints, and catchpoints if you do not
know which numbers to use.
   A breakpoint, watchpoint, or catchpoint can have any of four
different states of enablement:
   * Enabled.  The breakpoint stops your program.  A breakpoint set
     with the `break' command starts out in this state.
   * Disabled.  The breakpoint has no effect on your program.
   * Enabled once.  The breakpoint stops your program, but then becomes
     disabled.
   * Enabled for deletion.  The breakpoint stops your program, but
     immediately after it does so it is deleted permanently.  A
     breakpoint set with the `tbreak' command starts out in this state.
   You can use the following commands to enable or disable breakpoints,
watchpoints, and catchpoints:
`disable [breakpoints] [RANGE...]'
     Disable the specified breakpoints--or all breakpoints, if none are
     listed.  A disabled breakpoint has no effect but is not forgotten.
     All options such as ignore-counts, conditions and commands are
     remembered in case the breakpoint is enabled again later.  You may
     abbreviate `disable' as `dis'.
`enable [breakpoints] [RANGE...]'
     Enable the specified breakpoints (or all defined breakpoints).
     They become effective once again in stopping your program.
`enable [breakpoints] once RANGE...'
     Enable the specified breakpoints temporarily.  GDB disables any of
     these breakpoints immediately after stopping your program.
`enable [breakpoints] delete RANGE...'
     Enable the specified breakpoints to work once, then die.  GDB
     deletes any of these breakpoints as soon as your program stops
     there.
   Except for a breakpoint set with `tbreak' (*note Setting
breakpoints: Set Breaks.), breakpoints that you set are initially
enabled; subsequently, they become disabled or enabled only when you
use one of the commands above.  (The command `until' can set and delete
a breakpoint of its own, but it does not change the state of your other
breakpoints; see *Note Continuing and stepping: Continuing and
Stepping.)
