vaccess(enum vtype type,
mode_t file_mode, uid_t uid,
gid_t gid, mode_t acc_mode,
struct ucred *cred);
vaccess() function checks if the credentials described in cred are sufficient to perform the operation described by acc_mode, based on the type, file_mode, uid, and gid arguments. These arguments would typically be based on the vnode being accessed.
file_mode is the current mode of the file
that is having access checked. The uid and
gid arguments are the user id and group id
representing the owner of the file. acc_mode describes
the operation desired. It should be one of
representing read, write, and execute, respectively.
vaccess() will return 0 on success, or a non-zero error value on failure.
