Error/Warning C214

Summary
*** Error/Warning C214

'Argument' Conversion: Non-Pointer to Pointer
Illegal Pointer Conversion

Description

This message indicates that the argument to a function (that is not a pointer type) was used where a pointer argument was required. Objects whose types are bit or float and arguments that are aggregates types cannot be converted to pointers. Other types may be converted to pointer types if possible.

Cause

This message is caused when you use a non-pointer (binary, constant, bit, float, or other) type in the place of a pointer as an argument to a function.

Resolution

To resolve this issue, you may explicitly cast the argument to the correct pointer type.

Example

The following example causes the compiler to generate this warning.

int i;
void func (int xdata *p);

void main (void)
  {
  func (i);  // i is implicitly cast to an int xdata pointer
  }
