The three RECORD_LAYER source files build progressively on each other, i.e.

the simplest is rec_layer_s23.c. This provides the most basic functions used

for version negotiation. Next rec_layer_s3.c adds the SSL/TLS layer. Finally

rec_layer_d1.c builds off of the SSL/TLS code to provide DTLS specific

capabilities. It uses some DTLS specific RECORD_LAYER component members which

should only be accessed from rec_layer_d1.c. These are held in the

The two RECORD_LAYER source files build on each other, i.e.

the main one is rec_layer_s3.c which provides the core SSL/TLS layer. The second

one is rec_layer_d1.c which builds off of the SSL/TLS code to provide DTLS

specific capabilities. It uses some DTLS specific RECORD_LAYER component members

which should only be accessed from rec_layer_d1.c. These are held in the

DTLS1_RECORD_LAYER struct.
