[英]How to make cscope display full file paths during search
当我使用cscope
搜索C符号或全局定义时,它将显示文件名和行号。 我想查看完整的文件路径,以便可以跳转到我的arch专用文件。 例如,在基于Linux代码库的cscope
上搜索__switch_to
全局定义时,我得到:
Global definition: __switch_to
File Line
0 process.c 297 struct task_struct *__switch_to(struct task_struct *prev,
1 switch_to.h 44 #define __switch_to(prev,next,last) do { \
2 process.c 202 struct task_struct *__switch_to(struct task_struct *old,
3 process.c 400 struct task_struct *__switch_to(struct task_struct *prev,
4 process_32.c 211 __switch_to(struct task_struct *prev, struct task_struct *next)
5 process.c 80 void *__switch_to(struct task_struct *from, struct task_struct *to)
6 process_32.c 248 __switch_to(struct task_struct *prev_p, struct task_struct *next_p)
7 process_64.c 272 __switch_to(struct task_struct *prev_p, struct task_struct *next_p)
现在,每个arch
的文件process.c
都不同。 如何使cscope
显示完整的文件路径?
使用args -pn运行cscope
-pn显示最后n个文件路径组件,而不是默认的(1)。 使用0根本不显示文件名。
使用cscope -p4运行并搜索__switch_to的全局定义,结果为
Global definition: __switch_to
