shuffile_abort()

void shuffile_abort	(	int	rc,
		const char *	fmt,
			...
	)

print abort message and kill run

shuffile_align_free()

void shuffile_align_free

(

void *

buf

)

frees a blocked allocated with a call to shuffile_align_malloc

shuffile_align_malloc()

void* shuffile_align_malloc	(	size_t	size,
		size_t	align
	)

allocates a block of memory and aligns it to specified alignment

shuffile_alltrue()

int shuffile_alltrue	(	int	flag,
		MPI_Comm	comm
	)

returns true (non-zero) if flag on each process in comm is true
