realpath

realpath(3X)															      realpath(3X)

NAME

       realpath - resolve pathname

SYNOPSIS


DESCRIPTION

       The  function  derives, from the pathname pointed to by file_name, an absolute pathname that names the same file, whose resolution does not
       involve or symbolic links.  The generated pathname is stored, up to a maximum of bytes, in the buffer pointed to by resolved_name.

RETURN VALUE

       On successful completion, returns a pointer to the resolved name.  Otherwise, returns a null pointer and sets errno to indicate the  error,
       and the contents of the buffer pointed to by resolved_name are undefined.

ERRORS

       The function will fail if:

	      Read or search permission was denied for a component of
				     file_name.

	      Either the	     file_name or resolved_name argument is a null pointer.

	      An error occurred while reading from the file system.

	      Too many symbolic links were encountered in resolving
				     path.

	      The		     file_name argument is longer than or a pathname component is longer than

	      A component of	     file_name does not name an existing file or file_name points to an empty string.

	      A component of the path prefix is not a directory.

       The function may fail if:

	      Pathname resolution of a symbolic link produced an intermediate result whose
				     length exceeds

	      Insufficient storage space is available.
