After running nm command on any object file from out put can we get to know that wheather a symbol is a call to a function or definition of function ?

I am searching a class and function definitions inside many .so files.
I have 3 files which contain the symbol but I don't know wheather they are calling that function and class or they actually define it.

The command I am using is -

nm libmonitor.so | grep "ETD"

here ETD is the class I am looking for.

Some of what you get is implementation defined. nm -f [filename]
should give you column values somewhat like this:

Code:

[Index]   Value      Size    Type  Bind  Other Shndx   Name

Bind is the column you want.
LOCAL, GLOBAL (external) means the symbol is defined within the object, UNDEF means
that the symbol is resolved in some other object.

See this to fine tune your nm output:

nm

Hello,

Thanks for the reply.
In my case I am getting below output from command nm -f

ETD::etd_insert() - 30964
.ETD::etd_insert() T 284088172 964

I want to know that is ETD and .ETD two different classes / symbol ?
does dot in starting of ETD signify anything ?

Thanks.
