2006-06-15 04:49:11 +08:00
The <<_fgets_r>> function is simply the reentrant version of
<<fgets>> and is passed an additional reentrancy structure
pointer: <[ptr]>.
2000-02-18 03:39:52 +08:00
RETURNS
<<fgets>> returns the buffer passed to it, with the data
filled in. If end of file occurs with some data already
accumulated, the data is returned with no other indication. If
no data are read, NULL is returned instead.
PORTABILITY
<<fgets>> should replace all uses of <<gets>>. Note however
that <<fgets>> returns all of the data, while <<gets>> removes
the trailing newline (with no indication that it has done so.)
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>.
