28 | # |
29 | # After the prototypes one can have |X=...|Y=... to define more types. |
30 | # A commonly used extra type is to define D to be equal to "type_data", |
31 | # for example "struct_hostent_data to" go with "struct hostent". |
32 | # |
33 | # Example #1: I_XSBWR means int func_r(X, type, char*, size_t, type**) |
34 | # Example #2: S_SBIE means type func_r(type, char*, int, int*) |
35 | # Example #3: S_CBI means type func_r(const char*, char*, int) |
