# 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`. A milter can check this 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. 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.
