In order to use OSAtomicDecrement (mac-specific atomic operation), I need to provide a 4-byte aligned SInt32.
I have googled for atomic increment and decrement operators on Mac OS X and found \"OSAtomic.h\", but it seems you can only use this in kernel开发者_Go百科 space.
The C# spec states in section 5.5 that reads and writes on certain types (namely bool, char, byte, sbyte, short, ushort, uint, int, float, and reference types) are guaranteed to be atomic.
Under most Unixes and Posix conforming operating systems performing an open() operating system call with the O_APPEND indicates to the OS that writes are to be atomic appen开发者_运维知识库d and write
I have a class Manager that is going to be accessed by multiple threads at the same time, I want to know if I did it the right way ?
Say you have the following class public class AccessStatistics { private final int noPages, noErrors; public AccessStatistics(int noPages, int noErrors) {
What do you mean by Atomic instructions? How does the fol开发者_如何转开发lowing become Atomic?
I have a table regionkey: areaid-- primary key, int region-- char(4) locale-- char(4) The entire rest of the database is foreign-keyed to areaid.In this table there is an index on (region, locale)
I need atomic operation code equivalent to following: __asm__ __volatile__ ( \" lock;\\n\" \" addl %1, %0; \\n\"
We know from the C# specification that reference read/writes are atomic. In a statement that accesses member of an ob开发者_JAVA技巧ject, will the reference also be accessed atomically?
