From: Andre Noll Date: Sat, 15 Mar 2008 18:09:53 +0000 (+0100) Subject: Move write_all() from net.c to fd.c. X-Git-Tag: v0.3.2~61^2~6 X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=d2a600590a2607d2bd729f3079aaec320efe7990;p=paraslash.git Move write_all() from net.c to fd.c. This way it can be used also for programs that don't need networking. --- diff --git a/fd.c b/fd.c index abad80a8..48e2faf9 100644 --- a/fd.c +++ b/fd.c @@ -15,6 +15,31 @@ #include "para.h" #include "error.h" +/* + * Write a buffer to a file descriptor, re-write on short writes. + * + * \param fd The file descriptor. + * \param buf The buffer to be sent. + * \param len The length of \a buf. + * + * \return Standard.
