stat(2) which uses the file path -- unless you have an open file
descriptor on the file, in which case use fstat(2).

 guys,
 
 access(filenamewithpath, F_OK) returned true  as Zero if i have access to it.
what
 do i use in C to tell me that a file is not empty?

This should do:

#include sys/types.h
#include sys/stat.h
...
struct stat sb;
off_t size;
if (!lstat(pathbuf, sb)) size = sb.st_size;
...
