=== ===

Increase counting semaohore's value by 1. If counting semaphore already has maximum value, then after execution, the service ##[[en:osa:ref:allservices:OS_IsEventError|OS_IsEventError]]## will return true.

##[[en:osa:ref:appendix:configuration|OS_ENABLE_CSEM]]## constant must be defined in ##[[en:osa:ref:appendix:configuration|OSAcfg.h]]##. Size of counting semaphores is defined by ##[[en:osa:ref:appendix:configuration#Data types|OS_CSEM_SIZE]]## constant

<note>
For PIC16, counting semaphores can only be allocated in **bank0** or **bank1**
</note>


=== Call allowed: ===
Not in interrupt


=== Parameters: ===
{| class = "fpl"
|-
|//''csem''//
|Counting semaphore. Variable of ##[[en:osa:ref:description:data_types#OST_CSEM|OST_CSEM]]## type
|}


=== Returns: ===

##[[en:osa:ref:allservices:OS_IsEventError|OS_IsEventError]]##() returns true if counting semaphore already has maximum value

=== Example: ===
<code cpp>
OST_CSEM csem;

void Task (void)
{
    for (;;) {
        /*...*/
        OS_Csem_Signal_Now(csem);
        /*...*/
    }
}
