# In func|inc|type|... a "S" means "type*", and a "R" means "type**".
# (The "types" are often structs, such as "struct passwd".)
#
# After the prototypes one can have |X=...|Y=... to define more types.
# A commonly used extra type is to define D to be equal to "type_data",
# for example "struct_hostent_data to" go with "struct hostent".
#
# Example #1: I_XSBWR means int  func_r(X, type, char*, size_t, type**)
# Example #2: S_SBIE  means type func_r(type, char*, int, int*)
# Example #3: S_CBI   means type func_r(const char*, char*, int)
