C4201: pragma <name> was not handled

[WARNING]

Description

A pragma was not used by the compiler. This may have different reasons: the pragma is intended for a different compiler by a typing mistake, the compiler did not recognize a pragma. Note that pragma names are case sensitive. there was no context, a specific pragma could take some action The segment pragma DATA_SEG, CODE_SEG, CONST_SEG and their aliases never issue this warning, even if they are not used.

Example
  #pragma TRAP_PROG

  
  // typing mistake: the interrupt pragma is called 
  TRAP_PROC

  
  void Inter(void) {

  
    ...

  
  }

  
Tips

Investigate this warning carefully. This warning can be mapped to an error if only pragmas are used which are known.
