+    void printheader(struct Header*);
+        Show attributes and values of a Header for the package.
+
+        input: pointer to Header, pass by reference of a struct.
+               Can not be NULL.
+
+    void printmeshheader(struct MeshHeader*);
+        Show attributes and values of a MeshHeader.
+
+        input: pointer to MeshHeader, pass by reference of a struct.
+               Can not be NULL.
+
+    void printbatch(struct Batch*);
+        Show attribute and values of a Batch and three sample position 
+        coordinates.
+
+        input: pointer to Batch, pass by reference of a struct.
+               Can not be NULL.
+
+    void printcoordinate(struct Coordinate*, unsigned int);
+
+        input: 
+            pointer to array of Coordinates.
+            Can not be NULL.
+            
+            unsigned int, for quantity of coordinates to be printed.
+

+                       unsigned int, 
+                       const char * const);
+        Retrives the i-th MeshHeader in a buffer.
+
+        input:
+            Pointer of a pointer to MeshHeader.
+            Pass by reference of a pointer to the function.
+            The pointer of MeshHeader can be NULL and will be set to point to
+            a region in the buffer.
+
+            unsigned int, the i-th instance of MeshHeader in the buffer.
+
+            const char*, the buffer containing the whole mesh package.
+
+        output:
+            true on success.
+
+            false when failing checks against segmentation faults.
+                If parameter 'struct MeshHeader**' is NULL.
+                If parameter 'const char*' is NULL.

+    bool getbatch(struct Batch*, 
+                  unsigned int offset, 
+                  const char * const);
+        Retrives the i-th Batch in a buffer.
+
+        input:
+            Pointer to a Batch.
+            Pass by reference of a struct to the function.
+            Can not be NULL.
+
+            unsigned int, the i-th instance of Batch in the buffer.
+
+            const char*, the buffer containing the whole mesh package.
+
+    output:
+        true on success.
+
+        false when failing checks against segmentation faults.
+            If parameter 'struct Batch*' is NULL.
+            If parameter 'const char*' is NULL.

+    bool getmesh(struct Mesh*, 
+                 unsigned int, 
+                 const char*,
+                 unsigned int);
+    Retrives the i-th Mesh in a buffer.
+
+    input:
+        Pointer to mesh.
+        Pass by reference of a struct to the function.
+
+        unsigned int, the i-th instance of Mesh in the buffer.
+
+        const char*, the buffer containing the whole mesh package.
+
+    output:
+        true on success.
+
+        false when failing checks against segmentation faults.
+            If parameter 'struct Mesh*' is NULL.
+            If attribute 'b' of parameter 'struct Mesh' is NULL.
+            if parameter 'const char*' is NULL.
+            When file size is detected to be too small for a given i-th
+            Mesh.
