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.
