access(2) System Calls Manual access(2)
Name
access - determine the accessibility of file
Syntax
#include <unistd.h>
accessible = access(path, mode)
int accessible;
char *path;
int mode;
Description
The system call, checks the given file path for accessibility according to mode. The argument mode is an inclusive OR of the bits R_OK,
W_OK, and X_OK. Specifying the argument mode as F_OK tests whether the directories leading to the file can be searched and whether the
file exists.
The real user ID and the group access list (including the real group ID) are used to verify permissions. This call is useful to set-UID
programs.
Note that only access bits are checked. The call may indicate that a directory is writeable, but an attempt to open the directory fails,
although files are present in the directory. Additionally, a file may appear to be executable, but fails unless the file is in proper for-
mat.
If a path cannot be found, or if the desired access modes are not granted, a -1 value is returned; otherwise, a 0 value is returned.
Diagnostics
Access to the file is denied if any of the following is true:
[EACCES] Permission bits of the file mode do not permit the requested access or search permission is denied on a component of the
path prefix. The owner of a file has permission checked with respect to the owner's read, write, and execute mode bits.
Members of the file's group, other than the owner, have permission checked with respect to the group's mode bits. All oth-
ers have permissions checked with respect to the other mode bits.
[EFAULT] The path points outside the process's allocated address space.
[EIO] An I/O error occurred while reading from or writing to the file system.
[ELOOP] Too many symbolic links were encountered in translating the pathname.
[ENAMETOOLONG] A path component length exceeds 255 characters or the length of path exceeds 1023 characters.
[ENOENT] The file referred to by path does not exist or the path points to an empty string and the environment defined is POSIX or
SYSTEM_FIVE.
[ENOTDIR] A component of the path prefix is not a directory.
[EROFS] Write access is requested for a file on a read-only file system.
[ESTALE] The file handle given in the argument was invalid. The file referred to by that file handle no longer exists or has been
revoked.
[ETIMEDOUT] A connect request or remote file operation fails because the connected party did not respond after a period of time deter-
mined by the communications protocol.
[ETXTBSY] Write access is requested for a pure procedure (shared text) file that is being executed.
