如何使用GDB删除单个断点？

Question

我可以在GDB中添加一个断点:

b <filename>:<line no>

如何删除特定位置的现有断点？

Answer 1

您可以列出断点:

info break

这将列出所有断点.然后可以通过相应的数字删除断点:

del 3

例如:

 (gdb) info b
 Num     Type           Disp Enb Address    What
  3      breakpoint     keep y   0x004018c3 in timeCorrect at my3.c:215
  4      breakpoint     keep y   0x004295b0 in avi_write_packet atlibavformat/avienc.c:513
 (gdb) del 3
 (gdb) info b
 Num     Type           Disp Enb Address    What
  4      breakpoint     keep y   0x004295b0 in avi_write_packet atlibavformat/avienc.c:513

Answer 2

试试这些(参考):

clear linenum
clear filename:linenum

Answer 3

您可以使用删除所有断点

del <start_breakpoint_num> - <end_breakpoint_num>

要查看start_breakpoint_num和end_breakpoint_num,请使用:

info break

Answer 4

用：

clear fileName:lineNum   // Removes all breakpoints at the specified line.
delete breakpoint number // Delete one breakpoint whose number is 'number'
