Vec gc p reserve

概要

• gcc-4.1.0/gcc/vec.cにて定義
• vecの大きさをreserveを元に変化させる

引数

• void *vec
• int reserve
• MEM_STAT_DECL

実装

  82 /* Ensure there are at least abs(RESERVE) free slots in VEC.  If
  83    RESERVE < 0 grow exactly, else grow exponentially.  As a special
  84    case, if VEC is NULL, and RESERVE is 0, no vector will be created. */
