This was a Virtual server running on ESX with a Netapp NFS data-store solution. Something screwed up the virtual disk... I rebooted it but obviously could not boot after that. It is fine, took me a few minutes to roll back the whole server to a previous snapshot.

Thanks!

read_allocate(3)						  Staden Package						  read_allocate(3)

NAME
read_allocate, read_deallocate - Allocate and deallocate the Read structure. SYNOPSIS
#include <Read.h> Read *read_allocate( int num_points, int num_bases); void read_deallocate( Read *read); DESCRIPTION
These functions create and destroy Read structures. The Read structure is a generalised in-memory data structure used for holding trace data information. read_allocate() creates a Read structure large enough to hold num_points trace sample points and num_bases called bases. The allocated data is then initialised to appropriate defaults, which are mainly zeros and null pointers. read_deallocate() destroys a previously created Read structure. It is not sufficient to simply use the free() call instead. RETURN VALUES
On successful completion, the read_allocate() function returns a pointer to a Read structure. Otherwise this function returns a null pointer. The read_deallocate() function returns no value. SEE ALSO
read_reading(3), fread_reading(3), write_reading(3), fwrite_reading(3) read_allocate(3)
