[openssl-users] FIPS methods and symlinks

[jonetsu]

Hello,

  To grasp how FIPS methods are called, and following one method
as an example, HMAC_Update() in hmac.c, we can see that if FIPS
mode is active then FIPS_hmac_update() will be called.  This is
fine although searching the sources for the physical definiton of
FIPS_hmac_update() does not yield any results.  How does the
symbolic links function, what ends up being executed in this case
and through which path ?

Thanks, regards.
