How to export external reference from a file of C source code?

[Jackie]

Dear all,

I want to have a list of external function calls and variables from a C
source file.
For example, a C file may use abs(), strcmp(), strncpy() from standard
liberary.
Usually, there will be a list file after compiler.
But, is there an utility that can analysis C source codes and list all
external reference?

I don't know if this helps.

The linker produce such a list as errors if you try to compile your
program without the libraries.

How about using "nm" on the compiled object file?
(i.e. "nm file.o | grep GLOB")

that command apparently renames "file.o" to "| grep GLOB". I'm not sure how
helpful that is to the OP.

Or perhaps its a bad idea giving offtopic answers in CLC.....
