libbb: code shrink fgets_str

2021-02-03T19:43:07+00:00

Use a NULL value of maxsz_p to indicate to xmalloc_fgets_internal()
that the caller doesn't care about the maximum size of the buffer.
This allows the default maximum size to be set once in
xmalloc_fgets_internal() instead of separately in each caller.

*: make GNU licensing statement forms more regular

2010-08-16T18:14:46+00:00

This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

Fix xmalloc_fgets_str so that it really does NOT strip terminator.

2007-12-26T20:44:45+00:00

Add xmalloc_fgetline_str which does strip terminator,
and use it in dpkg instead of xmalloc_fgets_str.
netstat: use xmalloc_fgets_str - allows to eat strings with NULs
(this fixes bug with some weird /proc/net/unix input)
