Limits of Other Integer Types

Macros that specify the minimum and maximum limits of the miscellaneous types declared in <stdint.h>.

Attention: The macros relating to wide characters are implemented only by MPLAB XC32 compilers. The macros relating to signals are not implemented by MPLAB XC8 for PIC MCUs. Limited support of signals is provided by MPLAB XC8 for AVR MCUs.

<stdint.h>

Remarks

Each macro name corresponds to the indicated type. The macro will expand to a constant expression suitable for use in #if preprocessing directives, and this expression shall have the same type as an object of the corresponding type converted according to the integer promotions.
