NAME

       rfio_access - check existence/accessibility of a file/directory

SYNOPSIS

       Under Unix:
       #include <sys/types.h>
       #include <unistd.h>
       #include "rfio_api.h"

       Under Windows/NT:
       #include <sys/types.h>
       #define R_OK 4
       #define W_OK 2
       #define X_OK 1
       #define F_OK 0
       #include "rfio_api.h"

       int rfio_access (const char *path, int amode);

DESCRIPTION

       rfio_access checks the existence or the accessibility of the file/directory path according
       to the bit pattern in amode using the real user ID.

       path   specifies the logical pathname relative  to  the  current  directory  or  the  full
              pathname.

       amode  the bit pattern is built by an OR of the constants defined in <unistd.h> under Unix
              or to be explicitly defined under Windows/NT:

              R_OK   test for read permission

              W_OK   test for write permission

              X_OK   test for search/execute permission

              F_OK   test for existence of the directory/file.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation  failed.  In
       the latter case, serrno is set appropriately.

ERRORS

       ENOENT       The named file/directory does not exist.

       EACCES       Search  permission  is  denied on a component of the path prefix or specified
                    access to the file itself is denied.

       EFAULT       path is a NULL pointer.

       ENOTDIR      A component of path prefix is not a directory.

       EINVAL       amode is invalid.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of  a  path  component
                    exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.
