Hi, I am currently inserting the following line into functions for
which I want to print the function info. However, this can be tedious
if the source code is large.
fprintf(stderr, "%s:%d:%s\n", __FILE__, __LINE__, __PRETTY_FUNCTION__);
Is there a way to automatically print the information of each function
being called using gdb?

Hope this is not too late, I've been catching up on my mail.

Don't know, but you can do (in the shell, and you
will need moreutils and gawk (gnu awk)):
for i in SOURCE; do
gawk '{ if($0 ~ /^{/){ printf("{\n fprintf(stderr, "
"\"%%s:%%d:%%s\n\", __FILE__, __LINE__, __PRETTY_FUNCTION__);\n");
} else { print $0; } }' $i | sponge $i;
done
To undo:
for i in SOURCE; do
grep -v 'fprintf(stderr, "%s:%d:%s\n", __FILE__, __LINE__, __PRETTY_FUNCTION__);' $i | sponge $i;
done
I've done similar things before, it's simple if you've formatted
your code nicely (and put your unions and structs in your headers)!
Sincerely,
David
