Using only zlib to create a zip archive with multiple files in C is a bit more involved since zlib doesn't provide a direct API for creating zip files. However, you can still do it by constructing the zip file format manually.

Here's a simple example of how to create a zip archive with multiple files using zlib in C:
```c
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <zlib.h>

#pragma pack(push, 1)
typedef struct {
    uint32_t signature;
    uint16_t version;
    uint16_t flags;
    uint16_t compression;
    uint16_t mod_time;
    uint16_t mod_date;
    uint32_t crc32;
    uint32_t compressed_size;
    uint32_t uncompressed_size;
    uint16_t filename_length;
    uint16_t extra_field_length;
} local_file_header;

typedef struct {
    uint32_t signature;
    uint16_t version_made_by;
    uint16_t version_needed;
    uint16_t flags;
    uint16_t compression;
    uint16_t mod_time;
    uint16_t mod_date;
    uint32_t crc32;
    uint32_t compressed_size;
    uint32_t uncompressed_size;
    uint16_t filename_length;
    uint16_t extra_field_length;
    uint16_t comment_length;
    uint16_t disk_number_start;
    uint16_t internal_file_attributes;
    uint32_t external_file_attributes;
    uint32_t local_header_offset;
} central_directory_file_header;

typedef struct {
    uint32_t signature;
    uint16_t disk_number;
    uint16_t cd_disk_number;
    uint16_t disk_entries;
    uint16_t total_entries;
    uint32_t cd_size;
    uint32_t cd_offset;
    uint16_t comment_length;
} end_of_central_directory_record;
#pragma pack(pop)

int compress_file(FILE *src, FILE *dst, uLong *crc, uLong *compressed_size);
void write_local_file_header(FILE *zip, const char *filename, uLong crc, uLong compressed_size, uLong uncompressed_size);
void write_central_directory_file_header(FILE *zip, const char *filename, uLong crc, uLong compressed_size, uLong uncompressed_size, uLong local_header_offset);
void write_end_of_central_directory_record(FILE *zip, int num_files, uLong central_directory_size, uLong central_directory_offset);

int main(int argc, char *argv[]) {
    if (argc < 3) {
        printf("Usage: %s <output_zip> <input_file1> <input_file2> ...\n", argv[0]);
        return 1;
    }

    FILE *zip = fopen(argv[1], "wb");
    if (!zip) {
        perror("fopen");
        return 1;
    }

    uLong central_directory_offset = ftell(zip);
    uLong central_directory_size = 0;
    int num_files = argc - 2;

    for (int i = 2; i < argc; ++i) {
        FILE *input = fopen(argv[i], "rb");
        if (!input) {
            perror("fopen");
            fclose(zip);
            return 1;
        }

        uLong local_header_offset = ftell(zip);
        uLong crc, compressed_size, uncompressed_size;

        write_local_file_header(zip, argv[i], 0, 0, 0); // Write a placeholder, we'll update it later
        int result = compress_file(input, zip, &crc, &compressed_size);
        if (result != Z_OK) {
            fprintf(stderr, "Error compressing file %s\n", argv[i]);
            fclose(input);
            fclose(zip);
```
zlib는 zip 파일 생성을 위한 직접 API를 제공하지 않기 때문에 zlib만 사용하여 C에서 여러 파일이 포함된 zip 아카이브를 생성하는 것은 조금 더 복잡합니다. 하지만 zip 파일 형식을 수동으로 구성하여 만들 수 있습니다.다음은 C에서 zlib를 사용하여 여러 파일이 포함된 zip 아카이브를 만드는 방법에 대한 간단한 예제입니다:```c#include <stdio.h>#include <string.h>#include <stdlib.h>#include <zlib.h>#프라그마 팩(푸시, 1)typedef 구조체 {    uint32_t 서명;    uint16_t 버전;    uint16_t flags;    uint16_t 압축;    uint16_t mod_time;    uint16_t mod_date;    uint32_t crc32;    uint32_t 압축_크기;    UINT32_T UNCOMPRESSED_SIZE;    UINT16_t 파일명_길이;    UINT16_T EXTRA_FIELD_LENGTH;} local_file_header;typedef 구조체 {    uint32_t 서명;    UINT16_t VERSION_MADE_BY;    uint16_t version_needed;    uint16_t flags;    uint16_t 압축;    uint16_t mod_time;    uint16_t mod_date;    uint32_t crc32;    uint32_t 압축_크기;    UINT32_T UNCOMPRESSED_SIZE;    UINT16_t 파일명_길이;    UINT16_T EXTRA_FIELD_LENGTH;    UINT16_t 주석_길이;    UINT16_T DISK_NUMBER_START;    UINT16_T INTERNAL_FILE_ATTITUDES;    UINT32_T EXTERNAL_FILE_ATTITUDES;    UINT32_T LOCAL_헤더_오프셋;} central_directory_file_header;typedef 구조체 {    uint32_t 서명;    UINT16_T DISK_NUMBER;    UINT16_T CD_DISK_NUMBER;    UINT16_T DISK_ENTRIES;    UINT16_T 총_항목;    UINT32_t CD_SIZE;    UINT32_t CD_OFFSET;    UINT16_T COMMENT_LENGTH;} END_OF_CENTRAL_DIRRECTORY_RECORD;#프라그마 팩(팝)int compress_file(FILE *src, FILE *dst, uLong *crc, uLong *compressed_size);void write_local_file_header(FILE *zip, const char *filename, uLong crc, uLong compressed_size, uLong uncompressed_size);void write_central_directory_file_header(FILE *zip, const char *filename, uLong crc, uLong 압축된_크기, uLong 압축되지 않은_크기, uLong local_header_offset); void write_central_directory_file_header(FILE *zip, const char *filename, uLong 압축된_size, uLong 압축되지 않은_크기)void write_end_of_central_directory_record(FILE *zip, int num_files, uLong central_directory_size, uLong central_directory_offset);int main(int argc, char *argv[]) {    if (argc < 3) {        printf("사용법: %s <출력_zip> <입력_파일1> <입력_파일2> ...\n", argv[0]);        반환 1;    }    FILE *zip = fopen(argv[1], "wb");    if (!zip) {        PERROR("FOPEN");        반환 1;    }    uLong central_directory_offset = ftell(zip);    uLong central_directory_size = 0;    int num_files = argc - 2;    for (int i = 2; i < argc; ++i) {        FILE *입력 = fopen(argv[i], "rb");        if (!input) {            PERROR("FOPEN");            fclose(zip);            반환 1;        }        uLong local_header_offset = ftell(zip);        uLong crc, 압축된_크기, 압축되지 않은_크기;        write_local_file_header(zip, argv[i], 0, 0, 0); // 플레이스홀더 작성, 나중에 업데이트할 것입니다.        int result = compress_file(input, zip, &crc, &compressed_size);        if (result != Z_OK) {            fprintf(stderr, "%s\n 파일을 압축하는 동안 오류가 발생했습니다.", argv[i]);            fclose(input);            fclose(zip);```
