* unbreak vwarn: print ": " before errno messageRich Felker2013-08-211-2/+5
| | | | | patch by Strake. this seems to be a regression caused by fixing the behavior of perror("") to match perror(0) at some point in the past.
* collapse euidaccess to a call to faccessatRich Felker2013-08-031-9/+1
| | | | | | it turns out Linux is buggy for faccessat, just like fchmodat: the kernel does not actually take a flags argument. so we're going to have to emulate it there.
* add legacy euidaccess function and eaccess alias for itRich Felker2013-08-031-0/+18
| | | | this is mainly for ABI compat purposes.
* add legacy function vallocRich Felker2013-08-021-0/+8
| | | | it was already declared in stdlib.h, but not defined anywhere.
* make err.h functions print __prognameRich Felker2013-05-181-0/+4
| | | | | | | patch by Strake. previously is was not feasible to duplicate this functionality of the functions these were modeled on, since argv[0] was not saved at program startup, but now that it's available it's easy to use.
* more close-on-exec fixes, mostly using new "e" flag to fopenRich Felker2012-09-291-1/+1

* cleanup src/linux and src/misc trees, etc.Rich Felker2012-09-0713-0/+302
previously, it was pretty much random which one of these trees a given function appeared in. they have now been organized into: src/linux: non-POSIX linux syscalls (possibly shard with other nixen) src/legacy: various obsolete/legacy functions, mostly wrappers src/misc: still mostly uncategorized; some misc POSIX, some nonstd src/crypt: crypt hash functions further cleanup will be done later.
