7.4.12 Indicating Antiquated Objects

The __deprecate specifier can be used to indicate that an object has limited longevity and should not be used in new designs. It is commonly used by the compiler vendor to indicate that compiler extensions or features can become obsolete, or that better features have been developed and should be used in preference.

Use the native keywords discussed in the Differences section to look up information on the semantics of this specifier.

Example

The following shows a function that uses the __deprecate keyword.

void __deprecate getValue(int mode)
{
//...
}

Differences

When targeting AVR MCUs using the MPLAB XC8 compiler or when using the other compilers, the deprecated attribute (note the different spelling to the CCI specifier) has been used to indicate that use of certain objects should be avoided, if possible.

Migration to the CCI

When building with MPLAB XC16, XC-DSC or XC32 compilers, or with the MPLAB XC8 compiler for AVR MCUs, change any occurrence of the deprecated attribute to __deprecate, for example, from:

int __attribute__(deprecated) intMask;

to:

int __deprecate intMask;

Caveats

None.
