and ftrylockfile(). - Modified the internal FILE structure to allow for thread locking. Note that this again requires that the library is rebuilt! - Added or modified macros for getc_unlocked(), getchar_unlocked(), putc_unlocked() and putchar_unlocked(). - Added rand_r(). - Added flockfile()/funlockfile() wrappers around all stdio functions. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14841 87f5fb63-7c3d-0410-a384-fd976d0f7a62
