This may be if interest also. (also stdio.h)

#define __flbf(p) ((void)sizeof(__filbuf(p)), ((FILE *)(p))->__flag & _IOLBF)
#define __freading(p) ((void)sizeof(__filbuf(p)), ((FILE *)(p))->__flag & 
_IOREAD)
#define __fwriting(p) ((void)sizeof(__filbuf(p)), ((FILE *)(p))->__flag & 
_IOWRT)
#define __freadable(p) (__freading(p) && __fpending(p))
#define __fwritable(p) (__fwriting(p) && __fpending(p) < __fbufsiz(p))

#define __fpurge(p) funflush(p)
