# Generate `file.c` and `file.h` from binary contents of `file.txt`:# `const unsigned char *file`: file contents as a byte string# `const size_t file_size`: file size

Integrating with CMake
In CMake:
# 1. Include file2c.cmake scriptinclude(path/to/file2c.cmake)
# 2. Generate C libraryadd_file2c(
new_library_targetINPUTinput_file_to_be_embedded# Optional: choose the name of the global variable/header file# Defaults to input file nameSYMBOLsome_c_symbol# Pass "TEXT" to embed contents as text, omit for binary contentsTEXT
)
# 3. Link the generated library with other targetstarget_link_libraries(my_existing_targetnew_library_target)
In C/C++:
// 1. Include generated header#include<some_c_symbol.h>// 2. Use the embedded contentsvoidprint_contents() {
printf("Content: %s\n", some_c_symbol);
printf("Size: %lu\n", some_c_symbol_size);
}
