implicit declaration of function 'getdelim'

I'm relatively new to this so bear with me...

Although the code executes fine, I'm getting a
warning: implicit declaration of function 'getdelim'
message from the compiler. Why is this?

This is a GTK+/Gnome program and I'm using getdelim() function to read the output of a command I'm executing using popen.

Did you check the man page?
       #define _GNU_SOURCE
       #include <stdio.h>

       ssize_t getline(char **lineptr, size_t *n, FILE *stream);
       ssize_t getdelim(char **lineptr, size_t *n, int delim, FILE *stream);
You need both "#define _GNU_SOURCE" and "#include <stdio.h>" in the file using getdelim(). If you have both and still get the error, then something funky is going on; a weird layout of header and implementation files in the project perhaps.

I would think those would be covered with my #include <gnome.h>

However, even if I put them in my code I still get the warning... so I guess this is going to be harder than I thought. Since I'm using Anjuta, I'll have to wait until I'm ready to embark on the getting to know my project files intimately-- which I'm not ready for yet

Thanks for your suggestions.
