Bruce,

Will the deprecated attribute stop the build as warns are converted to errors? 
Having warns as errors is a good idea IMO, as some warns will cause a problem 
in execution sometimes or portability.

One suggestion is we can ifdef out the code, but also place the deprecated 
attribute on the function. Then the #else side of the ifdef is the #define to 
use snprintf. This way if they enable the ifdef they must live with the problem 
of deprecation later. Does 1.7 not support the deprecated attribute, maybe that 
was your point. :-)

I see a lot of code using rte_snprintf and I hate to change all of the code, 
but it is a simple find/replace sed script.
It is up to you guys I was just suggesting a simple fix for this release 
instead of the next release.

Thanks
Keith

That could work, Keith.
However, I would suggest we make use of the gcc ?deprecated? function attribute 
in 1.8 to flag it for future removal in a subsequent release. [Ref: 
https://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html]. That?s what the 
attribute is there for.

Why not just convert it into a macro and ifdef out the code or remove it. This 
way it can we remove later or just kept for some backward compat reason.

#define rte_snprintf  snprintf

Bruce, Stephen,

It may be a duplicate, but people are likely using it.  I would assume
deprecate means don?t remove, but put in a comment that says please don?t
use and migrate your code away from it.

Thanks,

Gerald

Subject: [dpdk-dev] Why rte_snprintf at all?

Why does rte_snprintf exist? It seems like a misunderstanding or broken
implementation of snprintf in some other C library. For standard Glibc,
I get same result from rte_snprintf and snprintf for all inputs
including
boundary cases

It can indeed probably be deprecated in next release. Any objections?
