44#
45# After the prototypes one can have |X=...|Y=... to define more types.
46# A commonly used extra type is to define D to be equal to "type_data",
47# for example "struct_hostent_data to" go with "struct hostent".
48#
49# Example #1: I_XSBWR means int func_r(X, type, char*, size_t, type**)
50# Example #2: S_SBIE means type func_r(type, char*, int, int*)
51# Example #3: S_CBI means type func_r(const char*, char*, int)
