File and Path Function
int readlink(const char *filename, char *buffer, size_t size);
Internationalization (I18n) Function Overview
The readlink function gets the value of the symbolic link filename.
The filename that the link points to is copied into buffer.
This filename string is not null-terminated; readlink normally returns the number of
characters copied. The size argument specifies the maximum number of characters to
copy, usually the allocation size of buffer.
Note that if the return value equals size, then it will be unclear as to where or not there
was room for the entire filename. Therefore, increase the size of buffer and size
and call readlink again.
I18n Issues
Ensure that size is a byte value and that buffer is large enough to hold the
resulting single-byte or multibyte characters.
See Locale-Sensitive Length Functions for a discussion on multibyte
character sizes.
On ANSI UTF-16 platforms, use a conversion function to convert the
wide-character strings to multibyte-character strings and then call readlink.
See Pathnames for a discussion of path and filename considerations in
an internationalized application.
