path_readlink()

Read the value of a symlink Inputs:

• Fd dir_fd The base directory from which path is understood
• const char *path Pointer to UTF-8 bytes that make up the path to the symlink
• u32 path_len The number of bytes to read from path
• u32 buf_len Space available pointed to by buf Outputs:
• char *buf Pointer to characters containing the path that the symlink points to
• u32 buf_used The number of bytes written to buf
