2012-08-11	add bsd fgetln function	Rich Felker	1	-0/+1
	optimized to avoid allocation and return lines directly out of the stream buffer whenever possible.
2011-07-30	add proper fuxed-based locking for stdio	Rich Felker	1	-1/+1
	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.
2011-05-02	fix fclose return status logic, again	Rich Felker	1	-1/+2
	the previous fix was incorrect, as it would prevent f->close(f) from being called if fflush(f) failed. i believe this was the original motivation for using \| rather than \|\|. so now let's just use a second statement to constrain the order of function calls, and to back to using \|.
2011-05-01	fix undefined call order in fclose, possible lost output depending on compiler	Rich Felker	1	-1/+1
	pcc turned up this bug by calling f->close(f) before fflush(f), resulting in lost output and error on flush.
2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	1	-0/+21
