| | | | | | | | | | | | explaining of "what a C string is", and make it more clear that these functiosn BEHAVE EXACTLY LIKE snprintf with "%s"! (anyone who wants to write a 'strlcpy considered harmful' paper should probably write a 'strlcpy and snprintf considered harmful' paper instead). note to those from other projects reading this commit message: It would be very good if this new manual was picked up in your project. ok jmc millert krw

| | | | | | | | handling to fix up the alignment of 64bit arguments so that they do the same dance where _thread_sys_FOO is the real stub and FOO is a weak alias. For some of them, this is needed for cancellation handling. From discussions with fgsch@, ok millert@

* make -column lists pretty again;jmc2011-09-031-3/+3
| | | | | | | | | | specifically, rewrite them to permit some markup in the column headers, and use "Ta" instead of literal tabs; mandoc does not currently match groff 100%, but a mandoc fix may be some time off, and we've gone enough releases with poorly formatting column lists. in some cases i have rewritten the lists as -tag, where -column made little sense.
* in column lists, enforce the following ordering:jmc2011-08-301-3/+3
| | | | | | | | | .Bl -column header1 header2 ... <Bl flags> mixing things up confuses mandoc, and adding flags in can screw up the list. this hopefully just makes things a bit safer (and more consistent). (one more bit of work left and all column lists should format how we want)

* Up until now, malloc scanned the bits of the chunk bitmap fromotto2011-05-051-32/+24
| | | | | | | | | | | | | | | | | | position zero, skipping a random number of free slots and then picking the next free one. This slowed things down, especially if the number of full slots increases. This changes the scannning to start at a random position in the bitmap and then taking the first available free slot, wrapping if the end of the bitmap is reached. Of course we'll still scan more if the bitmap becomes more full, but the extra iterations skipping free slots and then some full slots are avoided. The random number is derived from a global, which is incremented by a few random bits every time a chunk is needed (with a small optimization if only one free slot is left). Thanks to the testers!
