The backslash and back tick might be particularly nasty in a shell script context. Also, since we've been using upper-case generated values for a while now, go with the flow and use them in the pathname search rotation. Notes: svn path=/head/; revision=35191
* Add FILE locking stubs for libc.John Birrell1998-04-1128-337/+211
| | | | | | | | | | | Change the FILE locking to support kernel threads when linked with libpthread (which you haven't see yet). This requires that libc become thread-safe and thread-aware, testing __isthreaded before attempting to do lock/unlock calls. The impact on non-threaded programs is minor. This change works with libc_r, so it's the best compromise. Notes: svn path=/head/; revision=35129

* Return back to BSD snprintf semantics which recent C9x standard adoptsAndrey A. Chernov1997-12-243-21/+23
| | | | | | | | | | | | | instead of Singe Unix, thanx Bruce for explaining, I am not realize standards war was there. But now, fix n == 0 case to not return error and fix check for too big n. Things left to do: check for overflow in arguments. Notes: svn path=/head/; revision=31980
* 1) Oops! Insert again if (n == 0) return 0.Andrey A. Chernov1997-12-242-10/+10
| | | | | | | | | | | | | | | | | | | | | | Final word is Bruce's quote: C9x specifies the BSD4.4-Lite behaviour: [#3] ... Thus, the null-terminated output has been completely written if and only if the returned value is less than n. It means that if we not have any null-terminated output as for n == 0 we can't return value less than n, so we forced to return value equal to n i.e. 0 The next good thing is glibc compatibility, of course. 2) Do check for too big n in machine-independent way. 3) Minor optimization assuming EOF is < 0 Notes: svn path=/head/; revision=31979
* Back out part related to "return 0 if n == 0" and return EOF as before.Andrey A. Chernov1997-12-242-6/+2
| | | | | | | | | | | | | | The main argument is that it is impossible to determine if %n evaluated or not when snprintf return 0, because it can happens for both n == 0 and n == 1. Although EOF here is good indication of the end of process, if n is decreased in the loop... Since it is already supposed in many places that EOF *is* negative, f.e. from Single Unix specs for snprintf "return ... a negative value if an output error was encountered" this not makes situation worse.

* snprintf return value fixes to conform Single Unix specs:Andrey A. Chernov1997-12-242-6/+16
| | | | | | | | | | | | | | | | | | | | | | | 1) if buffer size is smaller than arguments size, return buffer size, not arguments size as before. 2) if buffer size is 0, return 0, not EOF as before. (now it is compatible with Linux and Apache implementations too). NOTE: Single Unix specs says: If the value of n {buffer size} is zero on a call to snprintf(), an unspecified value less than 1 is returned. It means we can't return EOF since EOF can take *any* value in general not especially < 1. Better variant will be return -1 (it is less then 1 and different with n == 1 case) but -1 value is already occuped by EOF in our implementation, so we can't distinguish true IO error in that case. So 0 here is only possible case still conforming to Single Unix specs. Notes: svn path=/head/; revision=31966
* Comment that long double is poorly implemented, not that it is unimplemented.Bruce Evans1997-12-191-2/+3
| | | | Notes: svn path=/head/; revision=31871
* Fixed long double formats. They were mostly not implemented exceptBruce Evans1997-11-231-4/+7
| | | | | | | | | | | | | | on systems where long doubles are just doubles. FreeBSD hasn't been such a system since it started using gcc-2.5 many years ago. The fix is of low quality. It loses precision. scanf() of long doubles doesn't seem to be used much, but gdb-4.16 uses %Lg format in its expression parser if it thinks that the system supports printf'ing of long doubles. The symptom was that floating point literals were usually interpreted to be 0.0. Notes: svn path=/head/; revision=31359

* Rework previous commit.. I was confused by the number of diffs in the PRPeter Wemm1997-07-061-8/+29
| | | | | | | | | | | | | | | | | | | | and forgot what I was trying to do originally and accidently zapped a feature. :-] The problem is that we are converting a counted buffer in a malloc pool into a null terminated C-style string. I was calling realloc originally to shrink the buffer to the desired size. If realloc failed, we still returned the valid buffer - the only thing wrong was it was a tad too large. The previous commit disabled this. This commit now handles the three cases.. 1: the buffer is exactly right for the null byte to terminate the string (we don't call realloc). 2: it's got h.left = 0, so we must expand it to make room. If realloc fails here, it's fatal. 3: if there's too much room, we realloc to shrink it - a failed realloc is not fatal, we use the original buffer which is still valid.
