在C中将字符串作为文件句柄访问

#include <stdio.h>

FILE *fmemopen(void *buf, size_t size, const char *mode);

#include <stdio.h>

int main() {
    char str[100] = "Hello, World!";
    FILE *file = fmemopen(str, sizeof(str), "r");

    if (file != NULL) {
        char buffer[100];
        fgets(buffer, sizeof(buffer), file);
        printf("Read from string: %s\n", buffer);
        fclose(file);
    }

    return 0;
}
