DESCRIPTION
<<fread>> attempts to copy, from the file or stream identified by
<[fp]>, <[count]> elements (each of size <[size]>) into memory,
starting at <[buf]>. <<fread>> may copy fewer elements than
<[count]> if an error, or end of file, intervenes.
<<fread>> also advances the file position indicator (if any) for
<[fp]> by the number of @emph{characters} actually read.

<<_fread_r>> is simply the reentrant version of <<fread>> that
takes an additional reentrant structure pointer argument: <[ptr]>.
2000-02-18 03:39:52 +08:00
RETURNS
The result of <<fread>> is the number of elements it succeeded in
reading.
PORTABILITY
ANSI C requires <<fread>>.
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.

2006-06-14 Jeff Johnston <jjohnstn@redhat.com> * libc/include/stdio.h: Add new reentrant I/O prototypes for read/write functions. Change getc/putc macros to have reentrant underlying macros/functions. This includes __sgetc_raw_r, __sgetc_r, and __sputc_r. * libc/stdio/fgetc.c: Fix and/or add reentrant version to call new reentrant I/O functions/macros for reading/writing. * libc/stdio/fgets.c: Ditto. * libc/stdio/fputc.c: Ditto. * libc/stdio/fputs.c: Ditto. * libc/stdio/fread.c: Ditto. * libc/stdio/fseek.c: Ditto. * libc/stdio64/fseeko64.c: Ditto. * libc/stdio/fwrite.c: Ditto. * libc/stdio/getc.c: Ditto. * libc/stdio/getc_u.c: Ditto. * libc/stdio/getchar.c: Ditto. * libc/stdio/getchar_u.c: Ditto. * libc/stdio/putc.c: Ditto. * libc/stdio/putc_u.c: Ditto. * libc/stdio/putchar.c: Ditto. * libc/stdio/puts.c: Ditto. * libc/stdio/vfprintf.c: Ditto. * libc/stdio/vfscanf.c: Ditto. * libc/stdio/fvwrite.c: Change __sfvwrite into reentrant __sfvwrite_r. Change all previous callers of __sfvwrite. Set errno to EBADF and set error flag on if attempt is made to write to file that does not allow writing. * libc/stdio/fvwrite.h: Fix new reentrant prototypes. * libc/stdio/local.h: Ditto. * libc/stdio/refill.c: Turn __srefill into reentrant __srefill_r. Set errno to EBADF and the error flag on if attempt is made to read unreadable file. Change all previous callers of __srefill. * libc/stdio/rget.c * libc/stdio/wbuf.c: Turn __swbuf into reentrant __swbuf_r. Change all previous callers of __swbuf. * libc/sys/linux/machine/i386/huge_val.h: Ifdef out file contents since huge value macros are already defined correctly for i386 by <math.h>.
