In today's episode of exposing useful Linux system calls I am exposing
preadv2 in this PR:
as requested in this issue:
As njsmith has commented in the PR, preadv2 only exists because regular
preadv was missing a flags argument, and in C the only way to add an
argument is to make a new function. In Python we have already exposed
preadv2 and a possible solution would be add a optional argument that
passes the new parametera to preadv and calls preadv2 if this happens.
On the other side, we have pipe and pipe2 as an example of exposing two
versions when this situation happens.
The question is:
What is preferable, exposing both functions or augment the old one?
Thank you everyone for your time!
