33 | # | |
34 | # After the prototypes one can have |X=...|Y=... to define more types. | |
35 | # A commonly used extra type is to define D to be equal to "type_data", | |
36 | # for example "struct_hostent_data to" go with "struct hostent". | |
37 | # | |
38 | # Example #1: I_XSBWR means int func_r(X, type, char*, size_t, type**) | |
39 | # Example #2: S_SBIE means type func_r(type, char*, int, int*) | |
