Thanks!
The content of a symbolic link is a string. When the symbolic link is encountered while traversing a pathname, you will get an error if that string (when incorporated into the pathname being evaluated) doesn't resolve to a file of the type expected for the operation being performed. There is no requirement that the contents of the symbolic link can be used to access a file at the time the symbolic link is created.
If a symbolic link is not used in pathname expansion, you can use use readlink() (the function), readlink (the utility [not available on all systems]), or ls (the utility with the -l option), to read the contents of the symbolic link when it is not being used for its normal purpose.

readlink
readlink(2) System Calls readlink(2)
NAME
readlink - read the contents of a symbolic link
SYNOPSIS
#include <unistd.h>
ssize_t readlink(const char *restrict path, char *restrict buf, size_t bufsiz);
DESCRIPTION
The readlink() function places the contents of the symbolic link referred to by path in the buffer buf which has size bufsiz. If the num-
ber of bytes in the symbolic link is less than bufsiz, the contents of the remainder of buf are left unchanged. If the buf argument is not
large enough to contain the link content, the first bufsize bytes are placed in buf.
RETURN VALUES
Upon successful completion, readlink() returns the count of bytes placed in the buffer. Otherwise, it returns -1, leaves the buffer
unchanged, and sets errno to indicate the error.
ERRORS
The readlink() function will fail if:
EACCES Search permission is denied for a component of the path prefix of path.
EFAULT path or buf points to an illegal address.
EINVAL The path argument names a file that is not a symbolic link.
EIO An I/O error occurred while reading from the file system.
ENOENT A component of path does not name an existing file or path is an empty string.
ELOOP A loop exists in symbolic links encountered during resolution of the path argument.
ENAMETOOLONG The length of path exceeds {PATH_MAX}, or a pathname component is longer than {NAME_MAX} while _POSIX_NO_TRUNC is in
effect.
ENOTDIR A component of the path prefix is not a directory.
ENOSYS The file system does not support symbolic links.
The readlink() function may fail if:
EACCES Read permission is denied for the directory.
ELOOP More than {SYMLOOP_MAX} symbolic links were encountered in resolving path.
ENAMETOOLONG As a result of encountering a symbolic link in resolution of the path argument, the length of the substituted pathname
string exceeded {PATH_MAX}.
USAGE
Portable applications should not assume that the returned contents of the symbolic link are null-terminated.
