* Here is an example:\verbatim GRAS_DEFINE_TYPE(s_clause,
struct s_array {
+ xbt_string_t name;
struct s_array *father GRAS_ANNOTE(size,1);
int length;
int *data GRAS_ANNOTE(size,length);
int *matrix GRAS_ANNOTE(size,rows*cols);
}
;)\endverbatim
- * It specifies that the structure s_array contains five fields, that the \a father field is a simple reference,
- * that the size of the array pointed by \a data is the \a length field, and that the \a matrix field is an array
- * which size is the result of \a rows times \a cols.
+ * It specifies that the structure s_array contains six fields, that the \a name field is a classical null-terminated
+ * char* string (#xbt_string_t is just an helper type defined exactly to help the parsing macro to specify the semantic of the pointer),
+ * that \a father field is a simple reference, that the size of the array pointed by \a data is the \a length field, and that the
+ * \a matrix field is an arraywhich size is the result of \a rows times \a cols.
*
* \warning Since GRAS_DEFINE_TYPE is a macro, you shouldn't put any comma in your type definition
* (comma separates macro args). For example, change \verbatim int a, b;\endverbatim to \verbatim int a;
}\endverbatim
*
* If you want to split this in two files (one for each kind of processes),
- * you need to put the GRAS_DEFINE_TYPE block in a separate header. But
+ * you need to put the GRAS_DEFINE_TYPE block in a separate header (so that
+ * each process kind see the associated C type definition). But
* then you cannot include this right away in all files because the extra
- * symbols would be defined in dupplicate.
+ * symbols containing the GRAS definition would be dupplicated.
*
- * You thus have to decide in which file the symbols will live. In that
+ * You thus have to decide in which C file the symbols will live. In that
* file, include the header without restriction:
*
\verbatim #include "my_header.h"
}\endverbatim
* And in the other files needing the C definitions without the extra GRAS
- * symbols, declare the symbol GRAS_DEFINE_TYPE_EXTERN before:
+ * symbols, declare the symbol GRAS_DEFINE_TYPE_EXTERN before loading gras.h:
*
\verbatim #define GRAS_DEFINE_TYPE_EXTERN
+#include <gras.h>
#include "my_header.h"
int server(int argc, char *argv[]) {
...
}\endverbatim
+ *
+ * Sometimes, the situation is even more complicated: There is some shared
+ * messages that you want to see from every file, and some private messages
+ * that you want to be defined only in one C file.
+ * In that case, use the previous trick for common messages, and use
+ * #GRAS_DEFINE_TYPE_LOCAL for the private messages.
+ *
+ * For now, there is no way to have semi-private symbols (for example shared
+ * in all files of a library), sorry. Use functions as interface to your
+ * library instead of publishing directly the messages.
