From 12e09f9f85ac48ff891adf92f3b2c9a5fea27273 Mon Sep 17 00:00:00 2001 From: Nicholas Noll Date: Sat, 4 Dec 2021 14:10:21 -0800 Subject: Chore(REMOVE): finished deprecation of old io functions. The old methods were simple wrappers of C standard library functions. We've moved (painfully) over to a new interface that allows for files to live on the stack. All users of the functionality are ported over. --- src/base/io/vprint.c | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 src/base/io/vprint.c (limited to 'src/base/io/vprint.c') diff --git a/src/base/io/vprint.c b/src/base/io/vprint.c new file mode 100644 index 0000000..6fa446e --- /dev/null +++ b/src/base/io/vprint.c @@ -0,0 +1,34 @@ +#include "internal.h" + +static int +flush(fmt·State *fmt) +{ + io·Header *io = fmt->file; + io->olen = fmt->buffer.cur - fmt->buffer.end; + if(io·flush(io)) + return 0; + + fmt->buffer.end = (char*)io->e; + fmt->buffer.cur = fmt->buffer.beg = fmt->buffer.end + io->olen; + return 1; +} + +int +io·vprint(io·Header *io, char *fmt, va_list args) +{ + int n; + fmt·State f; + + f.buffer.end = (char*)io->e; + f.buffer.beg = f.buffer.cur = (char*)(io->e + io->olen); + f.n = 0; + f.file = io; + f.flush = flush; + + va_copy(f.args,args); + n = fmt·do(&f, fmt); + va_end(f.args); + + io->olen = f.buffer.cur - f.buffer.beg; + return n; +} -- cgit v1.2.1
