打开gzip文件以便在C中读取而不创建临时文件

#include <stdio.h>
#include <zlib.h>

int main() {
    FILE *fp;
    char buf[2048];
    int gz_ret;

    fp = fopen("example.gz", "rb"); // 打开 gzip 文件
    if (!fp) {
        fprintf(stderr, "Error opening gzip file\n");
        return 1;
    }

    gz_ret = gzread(fp, buf, sizeof(buf)); // 调用 gzread 函数

    if (gz_ret == Z_OK) {
        printf("Read %d bytes from gzip file: ", gz_ret);
        gzgets(fp, buf, sizeof(buf));
        printf("%s\n", buf);
    } else {
        fprintf(stderr, "Error reading from gzip file: %d\n", gz_ret);
    }

    fclose(fp);
    return 0;
}
