Subject: fd: Modify xwrite() and write_all() to take void * buffer argument.
X-Git-Url: https://git.tuebingen.mpg.de/?a=commitdiff_plain;h=88f32f1aee78700647bd1f834e592cdb5e8adbf7;p=paraslash.git

fd: Modify xwrite() and write_all() to take void * buffer argument.

That's what the underlying call to writev(2) expects.
