The __P is a macro - you'll be able to find the definition in the includes part of the sources you are looking at.

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!
