Allocator type for GC vectors. Notice that we need the structure
declaration even if GC is not enabled.
template<typename
T , typename A >
void va_gc::reserve |
( |
vec< T, A, vl_embed > *& | v, |
|
|
unsigned | reserve, |
|
|
bool exact | MEM_STAT_DECL ) |
Allocator for GC memory. Ensure there are at least RESERVE free
slots in V. If EXACT is true, grow exactly, else grow
exponentially. As a special case, if the vector had not been
allocated and RESERVE is 0, no vector will be created.
