我正在使用 json-c 来解析项目中的 json 文件。我尝试创建 json_tokener_parse 但这导致了段错误。任何人都可以检查并告诉我段错误的原因。
#include <sys/mman.h>
#include <sys/stat.h>
#include <fcntl.h> // O_RDONLY
#include<stdlib.h>
#include<stdio.h>
#include<unistd.h>
#include<json-c/json.h>
int main() {
int oflag = O_RDONLY;
const char *path = "file.json";
const int fd = open(path, oflag);
// use stat to find the file size
struct stat stat;
int ret = fstat(fd, &stat);
int mflags = MAP_SHARED; // information about handling the mapped data
int mprot = PROT_READ|PROT_WRITE; // access permissions to the data being mapped
size_t size = stat.st_size;
void *addr = mmap(NULL, size, mprot, mflags, fd, 0);
const char *file = (char *)addr;
json_object * jobj = json_tokener_parse(addr);
//json_parse(jobj);
}
