Subject: [PATCH 04/11] nss_files: Use generic result pointer in parse_line
|
||
|
|
||
|
As a result, all parse_line functions have the same prototype, except
|
||
|
for that producing struct hostent. This change is ABI-compatible, so
|
||
|
it does not alter the internal GLIBC_PRIVATE ABI (otherwise we should
|
||
|
probably have renamed the exported functions).
|
||
|
|
||
|
A future change will use this to implement a generict fget*ent_r
|
||
|
function.
