61 Note: the compile time version of libmilter is available in the macro
62 <CODE>SMFI_VERSION</CODE>.
63 To extract the major and minor version as well as the current patch level
64 from this macro, the macros
65 <CODE>SM_LM_VRS_MAJOR(v)</CODE>,
66 <CODE>SM_LM_VRS_MINOR(v)</CODE>, and
67 <CODE>SM_LM_VRS_PLVL(v)</CODE>
68 can be used, respectively.
69 A milter can check the
70 <CODE>SMFI_VERSION</CODE>
71 macro to determine which functions to use
72 (at compile time via C preprocessor statements).
73 Using this macro and the
74 <CODE>smfi_version()</CODE>
76 a milter can determine at runtime whether it has been (dynamically)
77 linked against the expected libmilter version.
78 Such a function should only compare the major and minor version,
80 i.e., the libmilter library will be compatible despite
81 different patch levels.
