试试这个

#include <stdio.h>
#include <string.h>

void output_text_data(FILE *fo){
    enum status {
        OUT, IN
    } st = OUT;

    char buff[128];
    FILE *fi = fopen(__FILE__, "r");
    if(fi==NULL) return;//need this c file in same directory

    while(fgets(buff, sizeof buff, fi)){
        if(strcmp(buff, "#endif\n") == 0)
            break;
        if(st == IN)
            fputs(buff, fo);
        if(strcmp(buff, "#if LIKE_HERE_DOCUMENT\n") == 0)
            st = IN;
    }
    fclose(fi);
}

int main(void){
    output_text_data(stdout);

    FILE *fp = fopen("output.txt", "w");
    output_text_data(fp);
    fclose(fp);
}

#if LIKE_HERE_DOCUMENT
