version_info function

The higher-level code calls the version_info function to get information about the version of the library. The prototype for this function is:

int version_info( i2c_libversion_t *version );

The version argument is a pointer to a i2c_libversion_t structure that this function must fill in. This structure is defined as follows:

typedef struct {
    unsigned char   major;
    unsigned char   minor;
    unsigned char   revision;
} i2c_libversion_t;

This function should set the members of this structure as follows:

version->major = I2CLIB_VERSION_MAJOR;
version->minor = I2CLIB_VERSION_MINOR;
version->revision = I2CLIB_REVISION;

The function must return:

0

Success.

-1

Failure.
