sig_atomic_t Type

Integer type of an object that can be accessed as an atomic entity, even in the presence of asynchronous interrupts.

Attention: This type is not implemented by MPLAB XC8.

Include

<signal.h>

Remarks

Objects of this type (a volatile signed char for MPLAB XC8 for AVR MCUs and an int for other compilers that support signals) can be accessed atomically by a signal handler.
