hi:
I have confused by the following declaration such as :
/* operations */
void *_cookie; /* cookie passed to io functions */
int (*_close) __P((void *));
int (*_read) __P((void *, char *, int));
fpos_t (*_seek) __P((void *, fpos_t, int));
int (*_write) __P((void *, const char *, int));
which are in stdio.h of bsd lite2 source code.
I do not understand this kind of declaration.I will be very approciate if anybody can answer me.
Thanks!
alex
