The caller must set this value to the maximum length that the Name member can contain. Because symbol names can vary in length, this data structure is allocated by the caller. This member is used so IMAGEHLP knows how much memory is available for use by the symbol name.
Name
This is a null-terminated ASCII string containing either the decorated or undecorated symbol name. If the buffer is not large enough for the complete symbol, then the name is truncated to MaxNameLength length.
