argv-array API ============== The argv-array API allows one to dynamically build and store NULL-terminated lists. An argv-array maintains the invariant that the `argv` member always points to a non-NULL array, and that the array is always NULL-terminated at the element pointed to by `argv[argc]`. This makes the result suitable for passing to functions expecting to receive argv from main(), or the link:api-run-command.html[run-command API]. The link:api-string-list.html[string-list API] is similar, but cannot be used for these purposes; instead of storing a straight string pointer, it contains an item structure with a `util` field that is not compatible with the traditional argv interface. Each `argv_array` manages its own memory. Any strings pushed into the array are duplicated, and all memory is freed by argv_array_clear(). Data Structures --------------- `struct argv_array`:: A single array. This should be initialized by assignment from `ARGV_ARRAY_INIT`, or by calling `argv_array_init`. The `argv` member contains the actual array; the `argc` member contains the number of elements in the array, not including the terminating NULL. Functions --------- `argv_array_init`:: Initialize an array. This is no different than assigning from `ARGV_ARRAY_INIT`. `argv_array_push`:: Push a copy of a string onto the end of the array. `argv_array_pushl`:: Push a list of strings onto the end of the array. The arguments should be a list of `const char *` strings, terminated by a NULL argument. `argv_array_pushf`:: Format a string and push it onto the end of the array. This is a convenience wrapper combining `strbuf_addf` and `argv_array_push`. `argv_array_pop`:: Remove the final element from the array. If there are no elements in the array, do nothing. `argv_array_clear`:: Free all memory associated with the array and return it to the initial, empty state. `argv_array_detach`:: Detach the argv array from the `struct argv_array`, transferring ownership of the allocated array and strings. `argv_array_free_detached`:: Free the memory allocated by a `struct argv_array` that was later detached and is now no longer needed.
