libfs aims to be a portable (OSX/Linux/Windows) and lightweight filesystem API written in ANSI C.
Get the current working directory:
char cwd[MAX_PATH];
fs_current_dir(&cwd, MAX_PATH);Check if a file exists:
char buf[MAX_PATH];
fs_join_path(&buf, MAX_PATH, cwd, "foo.txt");
if (!fs_exist(buf))
{
printf("file not found: %s\n", buf);
}Read whole file content:
int size;
void* data = fs_read_file(buf, &size);
if (data == NULL)
{
printf("can't read file");
}
else
{
printf("file size: %d\n", size);
}
free(data);List a directory:
struct fs_directory_iterator* it = fs_open_dir(cwd);
while(fs_read_dir(it))
{
prinf("%s", it->path);
}
fs_close_dir(it);Check the documentation to find more examples and learn about the API.
Copy the files fs.c and fs.h into an existing project.
Comment or uncomment the defines at the top of fs.h depending on your configuration:
/* Define to 1 if you have the <stdio.h> header file. */
#ifndef HAVE_STDIO_H
#define HAVE_STDIO_H 1
#endif
/* Define to 1 if you have the <stdlib.h> header file. */
#ifndef HAVE_STDLIB_H
#define HAVE_STDLIB_H 1
#endif
/* Define to 1 if you have the <sys/stat.h> header file. */
#ifndef HAVE_SYS_STAT_H
#define HAVE_SYS_STAT_H 1
#endif
...You should now be able to compile this library correctly.
Tested with CMake >= 3.13.4:
git clone https://github.com/Nauja/libfs.git
cd libfs
git submodule init
git submodule update
mkdir build
cd build
cmake ..
CMake will correctly configure the defines at the top of fs.h for your system.
You can then build this library manually as described above, or by using:
cmake --build .
This will generate libfs.a if building as a static library and liblibfs.so in the build directory.
You can change the build process with a list of different options that you can pass to CMake. Turn them on with On and off with Off:
-DLIBFS_STATIC=On: Enable building as static library. (on by default)-DLIBFS_SHARED=On: Enable building as shared library. (on by default)-DLIBFS_UNIT_TESTING=On: Enable building the tests. (on by default)-DLIBFS_DOXYGEN=On: Enable building the docs. (off by default)
Generate the Visual Studio solution with:
mkdir build
cd build
cmake .. -G "Visual Studio 16 2019"
You can now open build/libfs.sln and compile the library.
