The SymGetOptions function retrieves the current options mask.
DWORD SymGetOptions(VOID);
This function has no parameters.
The SymGetOptions function always returns the current options mask. Zero is a valid value and indicates that all options are turned off. The options values are masks that are combined using the OR operator to form a valid options value. The valid mask values are:
| Value | Meaning |
|---|---|
| SYMOPT_CASE_INSENSITIVE | All symbol searches are insensitive to case. |
| SYMOPT_UNDNAME | All symbols are presented in undecorated form. |
| SYMOPT_DEFERRED_LOADS | Symbols are not loaded until a reference is made requiring the symbols be loaded. This is the fastest, most efficient way to use the symbol handler. |
| SYMOPT_NO_CPP | All C++ decorated symbols containing the symbol separator "::" are replaced by "__". This option exists for debuggers that cannot handle parsing real C++ symbol names. |
The options value can be changed several times while ImageHlp is in use by an application. The option change affects all future calls to the symbol handler.
To set the current options mask, use the SymSetOptions function.
