annotate lib/strndup.c @ 7379:3ee6e46a13c3
[lib/ChangeLog]
This function could end up with a definition for a function
named __strndup, rather than rpl_strndup on a system with
incomplete weak_alias support.
* strndup.c (strndup): Rename from __strndup.
Remove #defines that used to map __strndup to strndup.
Don't use K&R prototypes.
Remove LIBC-related code, since this file is not sync'd with glibc.
* strndup.h: Revamp, accordingly.
[m4/ChangeLog]
* strndup.m4: Modernize.
