How can I get a name of function running currently.

[Yeounkun, Oh]

Hello,

I want to know the name of function() in program.
In "gcc", I know that __FUNCTION__ macro is used for getting that.
but in "cc", __FUNCTION__ macro does not exist.
I can't find function to get the name of function running currently.
Could anybody help me?
Thanks.

ps. OS is SunOS 5.8

Regards.

__FUNCTION__ is a gcc extension. C99 defines __func__ as a "predefined
identifier" which will evaluate to a variable of type char[] (or static
const char[] to be precise) containing the name of the function in which
it is evaluated. There is no C89 equivalent but most compilers that
support any of the C99 standard support __func__ and many others have a
similiar extension. You don't have to do anything special to make this
functionality available (outside setting your compiler to c99 mode if
applicable).

<OT>
gcc considers __FUNCTION__ to be deprecated and newer versions treat it
the same as __func__ (there are some minor differences between the two),
you should avoid using the gcc extension for portability reasons. </OT>

Pre C-99 there is no standard way of doing this. __FUNCTION__ is an
addtion added by gcc. C99 you can use __func__
