+.Sh DESCRIPTION
+.Fn SSL_CTX_set_max_send_fragment
+and
+.Fn SSL_set_max_send_fragment
+set the
+.Sy max_send_fragment
+parameter for SSL_CTX and SSL objects respectively.
+This value restricts the amount of plaintext bytes that will be sent in
+any one SSL/TLS record.
+By default its value is SSL3_RT_MAX_PLAIN_LENGTH (16384). These
+functions will only accept a value in the range 512 -
+SSL3_RT_MAX_PLAIN_LENGTH.
+.Pp
+These functions are implemented using macros.
+.Sh RETURN VALUES
+These functions return 1 on success or 0 on failure.
