18 May 2009, Stefan Ritt, Suggestion, Question about using mvmestd.h

[CODE]int mvme_open(MVME_INTERFACE **vme, int idx)[/CODE]

[quote="Exaos Lee"]The definition of mvme_read_value is as the following:

03 Sep 2009, Stefan Ritt, Forum, Why should we use "INLINE" here?
|
[quote="Exaos Lee"]There are many "INLINE" definitions in "include/*.h". Both GNU C and C99 permit using inline functions. I still wonder why. :-)[/quote]
The INLINE statements are a relict from times where a subroutine call was in the order of a few microseconds. This was when you probably were pretty young, |
