These templates are implemented with macros, as we're not in C++ land. The interface functions are typesafe and use static inline functions, sometimes backed by out-of-line generic functions. The vectors are designed to interoperate with the GTY machinery. Because of the different behavior of structure objects, scalar objects and of pointers, there are three flavors, one for each of these variants. Both the structure object and pointer variants pass pointers to objects around -- in the former case the pointers are stored into the vector and in the latter case the pointers are dereferenced and the objects copied into the vector. The scalar object variant is suitable for int-like objects, and the vector elements are returned by value. There are both 'index' and 'iterate' accessors. The iterator returns a boolean iteration condition and updates the iteration variable passed by reference. Because the iterator will be inlined, the address-of can be optimized away. The vectors are implemented using the trailing array idiom, thus they are not resizeable without changing the address of the vector object itself. This means you cannot have variables or fields of vector type -- always use a pointer to a vector. The one exception is the final field of a structure, which could be a vector type. You will have to use the embedded_size & embedded_init calls to create such objects, and they will probably not be resizeable (so don't use the 'safe' allocation variants). The trailing array idiom is used (rather than a pointer to an array of data), because, if we allow NULL to also represent an empty vector, empty vectors occupy minimal space in the structure containing them. Each operation that increases the number of active elements is available in 'quick' and 'safe' variants. The former presumes that there is sufficient allocated space for the operation to succeed (it dies if there is not). The latter will reallocate the vector, if needed. Reallocation causes an exponential increase in vector size. If you know you will be adding N elements, it would be more efficient to use the reserve operation before adding the elements with the 'quick' operation. This will ensure there are at least as many elements as you ask for, it will exponentially increase if there are too few spare slots. If you want reserve a specific number of slots, but do not want the exponential increase (for instance, you know this is the last allocation), use the reserve_exact operation. You can also create a vector of a specific size from the get go. You should prefer the push and pop operations, as they append and remove from the end of the vector. If you need to remove several items in one go, use the truncate operation. The insert and remove operations allow you to change elements in the middle of the vector. There are two remove operations, one which preserves the element ordering 'ordered_remove', and one which does not 'unordered_remove'. The latter function copies the end element into the removed slot, rather than invoke a memmove operation. The 'lower_bound' function will determine where to place an item in the array using insert that will maintain sorted order. When a vector type is defined, first a non-memory managed version is created. You can then define either or both garbage collected and heap allocated versions. The allocation mechanism is specified when the type is defined, and is therefore part of the type. If you need both gc'd and heap allocated versions, you still must have *exactly* one definition of the common non-memory managed base vector. If you need to directly manipulate a vector, then the 'address' accessor will return the address of the start of the vector. Also the 'space' predicate will tell you whether there is spare capacity in the vector. You will not normally need to use these two functions. Vector types are defined using a DEF_VEC_{O,P,I}(TYPEDEF) macro, to get the non-memory allocation version, and then a DEF_VEC_ALLOC_{O,P,I}(TYPEDEF,ALLOC) macro to get memory managed vectors. Variables of vector type are declared using a VEC(TYPEDEF,ALLOC) macro. The ALLOC argument specifies the allocation strategy, and can be either 'gc' or 'heap' for garbage collected and heap allocated respectively. It can be 'none' to get a vector that must be explicitly allocated (for instance as a trailing array of another structure). The characters O, P and I indicate whether TYPEDEF is a pointer (P), object (O) or integral (I) type. Be careful to pick the correct one, as you'll get an awkward and inefficient API if you use the wrong one. There is a check, which results in a compile-time warning, for the P and I versions, but there is no check for the O versions, as that is not possible in plain C. Due to the way GTY works, you must annotate any structures you wish to insert or reference from a vector with a GTY(()) tag. You need to do this even if you never declare the GC allocated variants. An example of their use would be, DEF_VEC_P(tree); // non-managed tree vector. DEF_VEC_ALLOC_P(tree,gc); // gc'd vector of tree pointers. This must // appear at file scope. struct my_struct { VEC(tree,gc) *v; // A (pointer to) a vector of tree pointers. }; struct my_struct *s; if (VEC_length(tree,s->v)) { we have some contents } VEC_safe_push(tree,gc,s->v,decl); // append some decl onto the end for (ix = 0; VEC_iterate(tree,s->v,ix,elt); ix++) { do something with elt } */ /* Macros to invoke API calls. A single macro works for both pointer and object vectors, but the argument and return types might well be different. In each macro, T is the typedef of the vector elements, and A is the allocation strategy. The allocation strategy is only present when it is required. Some of these macros pass the vector, V, by reference (by taking its address), this is noted in the descriptions. */ /* Length of vector unsigned VEC_T_length(const VEC(T) *v); Return the number of active elements in V.

This works a little differently. Instead of DEF_VEC_ALLOC_P(TYPE, heap|gc), use DEF_VEC_ALLOC_P_STACK(TYPE). This uses alloca to get the initial space; because alloca can not be usefully called in an inline function, and because a macro can not define a macro, you must then write a #define for each type: #define VEC_{TYPE}_stack_alloc(alloc) \ VEC_stack_alloc({TYPE}, alloc) This is really a hack and perhaps can be made better. Note that this macro will wind up evaluating the ALLOC parameter twice. Only the initial allocation will be made using alloca, so pass a reasonable estimate that doesn't use too much stack space; don't pass zero.
