Interface GNUCLibrary

All Superinterfaces:

com.sun.jna.Library

public interface GNUCLibrary
extends com.sun.jna.Library

GNU C library.

Not available on all platforms (such as Linux/PPC, IBM mainframe, etc.), so the caller should recover gracefully in case of LinkageError. See HUDSON-4820.

Read a symlink. The name will be copied into the specified memory, and returns the number of bytes copied. The string is not null-terminated.

Returns:

if the return value equals size, the caller needs to retry with a bigger buffer. If -1, error.
