Rich Felker	835f9f950e	clean up stdio_impl.h this header evolved to facilitate the extremely lazy practice of omitting explicit includes of the necessary headers in individual stdio source files; not only was this sloppy, but it also increased build time. now, stdio_impl.h is only including the headers it needs for its own use; any further headers needed by source files are included directly where needed.	14 years ago
Rich Felker	8582a6e9f2	add 'e' modifier (close-on-exec) to fopen and fdopen this feature will be in the next version of POSIX, and can be used internally immediately. there are many internal uses of fopen where close-on-exec is needed to fix bugs.	14 years ago
Rich Felker	3b43d10faf	fdopen should set errno when it fails due to invalid mode string	14 years ago
Rich Felker	dba68bf98f	add proper fuxed-based locking for stdio previously, stdio used spinlocks, which would be unacceptable if we ever add support for thread priorities, and which yielded pathologically bad performance if an application attempted to use flockfile on a key file as a major/primary locking mechanism. i had held off on making this change for fear that it would hurt performance in the non-threaded case, but actually support for recursive locking had already inflicted that cost. by having the internal locking functions store a flag indicating whether they need to perform unlocking, rather than using the actual recursive lock counter, i was able to combine the conditionals at unlock time, eliminating any additional cost, and also avoid a nasty corner case where a huge number of calls to ftrylockfile could cause deadlock later at the point of internal locking. this commit also fixes some issues with usage of pthread_self conflicting with __attribute__((const)) which resulted in crashes with some compiler versions/optimizations, mainly in flockfile prior to pthread_create.	15 years ago
Rich Felker	eb0e8fa0b1	debloat: use __syscall instead of syscall where possible don't waste time (and significant code size due to function call overhead!) setting errno when the result of a syscall does not matter or when it can't fail.	15 years ago
Rich Felker	69cf09c821	avoid setting errno when checking for tty setting errno here is completely valid, but some programs, notably busybox printf, assume that errno will not be set during output and treat this as an error condition. in any case, skipping it slightly reduces code size and saves time.	15 years ago
Rich Felker	aa398f56fa	global cleanup to use the new syscall interface	15 years ago
Rich Felker	0b44a0315b	initial check-in, version 0.5.0	15 years ago
