DESCRIPTION

_S_S_L___g_e_t___f_d_(_) returns the file descriptor which is linked to ssssll. _S_S_L___g_e_t___r_f_d_(_) and _S_S_L___g_e_t___w_f_d_(_) return the file descriptors for the read or the write channel, which can be different. If the read and the write channel are different, _S_S_L___g_e_t___f_d_(_) will return the file descriptor of the read channel.

RETURN VALUES

The following return values can occur:
-1 The operation failed, because the underlying BIO is not of the correct type
(suitable for file descriptors).
>=0 The file descriptor linked to ssssll.
