Подтвердить способность клиента прочитать символьную ссылку
#include <sys/iofunc.h>int iofunc_readlink( resmgr_context_t *ctp,io_readlink_t *msg,iofunc_attr_t *attr,struct _client_info *info );

The iofunc_readlink() helper function supports readlink() requests by verifying that the client can read a symbolic link. It's similar to iofunc_open().
The iofunc_readlink() function checks to see if the client (described by the optional info structure) has access to open the resource (name passed in the msg structure). The attr structure describes the resource's attributes.
The info argument can be passed as NULL
, in which case iofunc_readlink() obtains the client information itself via a call to iofunc_client_info(). It is, of course, more efficient to get the client info once, rather than calling this function with NULL
every time.
The iofunc_readlink() function handles the readlink verification for the POSIX layer.
