From c0a50de92300080a1cf11bf4ff0ec3b2d6240c10 Mon Sep 17 00:00:00 2001 From: Josh Haberman Date: Tue, 21 Aug 2018 14:47:50 -0700 Subject: Removed a bunch of obsolete code. A lot of this code was experimental or temporarily useful, but is no longer needed. --- upb/bindings/stdc/io.h | 64 -------------------------------------------------- 1 file changed, 64 deletions(-) delete mode 100644 upb/bindings/stdc/io.h (limited to 'upb/bindings/stdc/io.h') diff --git a/upb/bindings/stdc/io.h b/upb/bindings/stdc/io.h deleted file mode 100644 index b131500..0000000 --- a/upb/bindings/stdc/io.h +++ /dev/null @@ -1,64 +0,0 @@ -/* -** ANSI C file I/O. -*/ - -#ifndef UPB_STDC_IO_H_ -#define UPB_STDC_IO_H_ - -#include -#include "upb/bytestream.h" - -UPB_BEGIN_EXTERN_C - -/* upb_stdio ******************************************************************/ - -// bytesrc/bytesink for ANSI C stdio, which is less efficient than posixfd, but -// more portable. -// -// Specifically, stdio functions acquire locks on every operation (unless you -// use the f{read,write,...}_unlocked variants, which are not standard) and -// performs redundant buffering (unless you disable it with setvbuf(), but we -// can only do this on newly-opened filehandles). - -typedef struct { - uint64_t ofs; - size_t len; - uint32_t refcount; - char data[]; -} upb_stdio_buf; - -// We use a single object for both bytesrc and bytesink for simplicity. -// The object is still not thread-safe, and may only be used by one reader -// and one writer at a time. -typedef struct { - upb_bytesrc src; - upb_bytesink sink; - FILE *file; - bool should_close; - upb_stdio_buf **bufs; - int nbuf; - uint32_t szbuf; -} upb_stdio; - -void upb_stdio_init(upb_stdio *stdio); -// Caller should call upb_stdio_flush prior to calling this to ensure that -// all data is flushed, otherwise data can be silently dropped if an error -// occurs flushing the remaining buffers. -void upb_stdio_uninit(upb_stdio *stdio); - -// Resets the object to read/write to the given "file."
