28 Built-in Functions

This appendix lists the built-in functions that are specific to MPLAB XC16 C Compiler.

Built-in functions give the C programmer access to assembler operators or machine instructions that are currently only accessible using inline assembly, but are sufficiently useful that they are applicable to a broad range of applications. Built-in functions are coded in C source files syntactically like function calls, but they are compiled to assembly code that directly implements the function and do not involve function calls or library routines.
