From 77a58cad3fa0a286bd2581187a2463a762d711ba Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 5 Dec 1995 03:35:55 +0000 Subject: Tue Dec 5 02:27:32 1995 Ulrich Drepper * libio/Makefile [routines]: Remove iofscanf, add iopopen, pclose. * libio/iofscanf.c: Remove file. * libio/iogetdelim.c (_IO_getdelim): Correct stupid bug at string termination. * libio/iopopen.c: New file from GNU libio. * libio/memstream.c: Fixed bug in fclose handling. Instead of providing a close callback we need a finish callback. * libio/pclose.c: New file. Derived from popen.c in GNU libio. * posix/gnu/types.h: Fixed typo. * stdio-common/errnobug.c: fputs returns EOF in error case. Do not test for != 0. * stdio-common/printf-parse.h (parse_one_spec): Do not force padding with ' ' if precision is given. Fix by HJ Lu. * stdio-common/printf_fp.c: Fix comment. * stdio-common/tfformat.c, stdio-common/tiformat.c, stdio-common/tstdiomisc.c: New files from GNU libio test suite. * stdio-common/tstgetln.c: Provide ssize_t type when testing libio. * stdio-common/vfprintf.c (outchar): Use PUTC instead of putc. (vfprintf): Cleasr args_type array before using it. When printing 0 as an integer with precision 0 nothing must be written for the number. Based on patch by HJ Lu. * stdio-common/vfscanf.c: Remove fixed input buffer. Now we have a dynamically extended buffer. * stdlib/strtod.c: Merge with version in Linux libc. This fixes some bugs with handling of very small numbers and has different solution for formaer patches. * sysdeps/i386/i586/add_n.S, sysdeps/i386/i586/sub_n.S: Rename macros r1 and r2 to t1, and t2 resp. This is necessary because glibc headers also define r1.
