# smfi_version()

SYNOPSIS

    #include <libmilter/mfapi.h>
    int smfi_version(
    	unsigned int *pmajor,
    	unsigned int *pminor,
    	unsigned int *ppl
    );

Get the (runtime) version of libmilter.

DESCRIPTION

Called When | smfi_version may be called at any time.
Effects | None.

ARGUMENTS

Argument | Description
--- | ---
pmajor | Pointer to an unsigned int variable to store major version number.
pminor | Pointer to an unsigned int variable to store minor version number.
ppl | Pointer to an unsigned int variable to store patch level number.

RETURN VALUES | smfi_version returns MI_SUCCESS.

Note: the compile time version of libmilter is available in the macro `SMFI_VERSION`. To extract the major and minor version as well as the current patch level from this macro, the macros `SM_LM_VRS_MAJOR(v)`, `SM_LM_VRS_MINOR(v)`, and `SM_LM_VRS_PLVL(v)` can be used, respectively. A milter can check the `SMFI_VERSION` macro to determine which functions to use (at compile time via C preprocessor statements). Using this macro and the `smfi_version()` function, a milter can determine at runtime whether it has been (dynamically) linked against the expected libmilter version. Such a function should only compare the major and minor version, not the patch level, i.e., the libmilter library will be compatible despite different patch levels.
