  13   15  DESCRIPTION
  14   16       The Pdelbkpt() function removes the breakpoint installed at address from
  15   17       process P.  Restoring the instruction present in saved.
  16   18  
  17   19       If the instruction at address is no longer the architecture-specific

  18   20       breakpoint instruction, then saved is not restored, but the function
  19   21       still returns successfully.  This behavior is done due to the presence of
  20   22       setting breakpoints in self-modifying code, e.g. procedure linkage
  21   23       tables.
  22   24  
  23   25       The Pdelbkpt() function only works on running processes, such as those
  24   26       created through Pgrab(3PROC) and Pcreate(3PROC).  Attempting to remove a
  25   27       breakpoint from process handles to core files, zombie processes, or ELF
  26   28       objects will fail.
  27   29  
  28   30  RETURN VALUES
  29   31       Upon successful completion, the Pdelbkpt() function removes the
  30   32       breakpoint and returns 0.  Otherwise, -1 is returned, and errno is set to
  31   33       indicate the error.

  33   35  ERRORS
  34   36       For a full list of possible errors see the DIAGNOSTICS section in
  35   37       proc(4).

  37   39       The Pdelbkpt() function will fail with:
  38   40  
  39   41       ENOENT             The handle P refers to a grabbed core file, a zombie
  40   42                          process, or an ELF object.
