SymUnDName

The SymUnDName function undecorates a decorated symbol.

This function is implemented as a wrapper that calls SymUnDName64. For more information, see New 64-bit Functions.

BOOL SymUnDName(
  PIMAGEHLP_SYMBOL Symbol,  
  PSTR UnDecName,       
  DWORD UnDecNameLength  
);

For SymUnDName64, the parameter list is as follows.

BOOL SymUnDName64(
  PIMAGEHLP_SYMBOL64 Symbol,  
  PSTR UnDecName,       
  DWORD UnDecNameLength  
);

Parameters

Symbol

[in] Specifies the symbol to be undecorated.

UnDecName

[out] Specifies the buffer that receives the undecorated symbol name.

UnDecNameLength
