I'm a little confused by your program dying without a core-dump. What do you mean by dying? Did it hang? Did you get any error code at all?<br />
<br />
Make sure you set your coredump size to be unlimited (use the following command):<br />
limit coredumpsize unlimited<br />
<br />
If you can give me a little more of your code, I might be able to help some more.<br />
Have you got access to a debugger?<br />

Please could anybody help.

File Locking on Solaris

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
