vector_c

std::vector in C++ implemented simply and minimally in C.
The repository contains general purpose one vector which you need to cast to specific struct and supply creation function with size of struct.

It allocate more memory space to reduce calling to expensive call to realloc(). It uses 1.5 as factor of increasing elements the same as in std::vector.

Build & Run

It's based on autotools. Execute the following

./autogen.sh
./configure
make
(optional) make check
make install - will install both static, shared library included header files to your system

Installation

Debian/Ubuntu

sudo add-apt-repository ppa:haxpor/combined
sudo apt install vector_c

NDK-BUILD support for Android

This project has support for building this library for Android.

It has Android.mk file at the root directory of this project. You can use the following commands

ndk-build NDK_PROJECT_PATH=null NDK_OUT=build/objs NDK_LIBS_OUT=build/libs APP_BUILD_SCRIPT=Android.mk APP_PLATFORM=android-18 APP_MODULES="vector vector_static" NDK_DEBUG=1

That will generate obj and library (shared and static one) files at build/objs and build/libs (static library is at build/objs/local for minimum sdk support of api level 18 with debugging symbols also generated. APP_MODULES tells to build for both shared and static library.

Note

Use vector.h and vector.c to integrate with your main source code.
See example code at vector_test.c.

This one will do deep copy for input data, so it won't be mess or broken when you change input data from outside, it's separate. It also accepts custom memory freeing function if your element needs a proper memory care. Just set its free_element function pointer to your function imeplementation via free_element(void* element) signature.

When using vector_clear() it will shrink down allocated memory to estimatedLen which is sent to vector_new() at first time, and will expand again if needed.
