[Freetype] do I have to release the memory explicitly?

[陈亮]

Hello,everyone
      I use the function FT_Load_Char in a loop,and do something with the 
face->glyph->outline data member.Do I have to release the memory hold by 
face->glyph explicitly?Or the freetype system will manage the memory 
automatically when I load the next char?
