Subject: [PATCH] cmdline: use freopen() to reopen standard streams
|
|
|
|
In glibc stdin, stdout & stderr are variables that can be assigned to
|
|
(https://www.gnu.org/software/libc/manual/html_node/Standard-Streams.html)
|
|
however this not necessarily true of other C libraries.
|
|
|
|
The gentoo musl porting notes
|
|
(https://wiki.gentoo.org/wiki/Musl_porting_notes)
|
|
recommend the substitution of
|
|
|
|
stdX = fopen(...)
|
|
|
|
with
|
|
|
|
freopen(..., stdX)
|
|
