+  PURPOSE : codes the content of a C-Structure into a bitstream.
+            This function may be called recursivly if an IE in the
+            structure is itself a structured IE.
+
+            For extended octet groups the following rules apply.
+            
+            Any IE within an extension octet is characterised by its 
+            extGroup which is one of the following:
+            
+            
+            '+'    octet begins with this IE.
+            ' '    octet continues with this IE or a new octet begins.
+            '-'    octet ends with this IE.
+            '*'    octet group ends with this IE.
+            
+            An octet may begin with '+', '-', ' ' or '*'.
+            An octet beginning with '-' or '*' is made of only one IE (7 bits).
+            A group made of one octet has only one IE with '*'.
+            If '+' is present, next IEs ending with '*' or '-' are present too.
+            If the beginning IE  with ' ' is not IE

+
+            ExtendedGroupActive is set to 1 if '+' is present in the encoding.
+            ExtendedGroupActive is changed from 1 to 0 when encoding '*'.
+            ExtendedGroupActive is set to 0 if an octet beginning with ' ' is
+            not present.
+            OpenNewOctet is set to 1 after encoding an IE with '-'.
+            ExtBitPos1 is set to the globs->bitpos when writing extension bit:
+            1) for '+' or 
+            2) for ' ' after '-'
+
+            Extension bit is set to 0 if a further octet is encoded for
+            the group. If an octet is the last one within a group, the 
+            extension bit is set to 1.
+
+            While processing the first IE of an octet (e.g. for '+'),
+            if the IE is absent, CCD will skip over all IEs up to the
+            ending '*'.
+            When processing IEs with ' ' and for ExtendedGroupActive=1 the valid
+            flag is set to 1 in order to compensate probable mistakes in PS.

+               0x81, 0x82 etc in the first byte to say L is encoded
+               in one, two etc bytes.
+               For ASN.1 BER type use 0x80 in the first byte and
+               two otets of 0 bits after the encoded IE.
+               For all the three types it is possible to encode L

+
+    PARAMETERS:  U8      entity
+		  - specifies the calling entity of CCD. The Constants
+		    for each valid entity is defined in MCONST.CDG
+
+		 U8      direction
+		  - specifies wether the message goes UPLINK or DOWNLINK.
+		    This is nessesary because there are same PDU-Type
+		    codes for different messages.
+
+		       U16 l_buf
+		  - Lenght of the bitstrem to be decoded.
+
+							   U16 o_buf
+		  - specifies the bitstream buffer of the message. The
+		    struct contains the l_buf and the o_buf elements.
+		    These elements specifies the length and offset in bits
+		    of the bitstream in the T_MSGBUF component buf.
+
+							   U8 *buf
+		  - specifies the bitstream buffer of the message. 
+
+		 U8 ** mStructPtr
+		  -	points to the pointer on the C-structure of the 
+		    decoded message. The buffer containing this message 
+		    structure will be allocated by CCD. After decoding 
+		    the first element in the message C-structure contains 
+		    the message (PDU) type as a UBYTE.
+
+		 U8  mId
+		  - specifies the PDU-Type of the bitstream. If this

+		    the pdu-type from the bitstream to decide wich decoding
+		    rules to select. Normaly this param is set to 0xff.
+
+    PURPOSE:     Like ccd_decodeMsg, this function decodes a bitstream
+		 containing a valid TETRA-Message from the Air-Interface
+		 to a corresponding C-Structure, only this function
+		 allows the use of pointer types in the C-structure.
