Exit the critical section, which is equivalent to applying for unlocking
The following sample code demonstrates how to use the critical section for Data Synchronization:
// Global variableInt icounter = 0;Critical_section cricounter;
DWORD threada (void * PD){Int IID = (INT) PD;For (INT I = 0; I {Entercriticalsection ( cricounter );Int icopy = icounter;Sleep (100 );Icounter = icopy
Because Process/There are many methods for synchronizing data between threads. Each method has different purposes:Critical Section,Mutex, Signal lights, events for synchronization.
Because the process/Operations between threads are performed in parallel, so a data synchronization problem occurs. Let's look at a piece of code first:
Int iCounter = 0; // global variable
DOWRD threadA (void * pD)
{
For (int I = 0; I
{
Int iCopy
sorting array elements based on their length. The shortest items are placed at the beginning:Listing ICopy codeThe Code is as follows:Print_r ($ data); function sortByLen ($ a, $ B ){If (strlen ($ a) = strlen ($ B )){Return 0;} Else {Return (strlen ($ a)> strlen ($ B ))? 1:-1;}}?> In this way, we have created our own comparison function. This function uses the strlen () function to compare the number of each string, and then returns 1, 0 or-1 respect
