Can I print the current function name in c? something like __LINE__?
for e.g
can I do
printf( " the current file is %s : function is : %s and line # is
:%d\n", __FILE__, __FUNC__, __LINE__);
thanks

__func__ is a a const char * and points to the current function name (for
C99). Gcc supported __FUNCTION__ and __PRETTY_FUNCTI ON__, but that's not
standard and has been deprecated.

for e.g
yes, in C99 you can use the predefined identifier __func__

That gives you the complete function signature (including name space and
classes in C++).

Doubly off-topic: particular compiler (gcc) and wrong language (not C).
Used to print the function name as it appears in the source
(__FUNCTION__) or "in a language-specific way" (__PRETTY_FUNCT ION__).
For C++, for example, __PRETTY_FUNCTI ON__ yields scoping information.

Actually it is a const char [] containing the current function name
(so you can do "sizeof" on it, and take its address, etc.) This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
