Thread: Problem reading struct outside of function

I have a struct that is declared outside main() for the purpose of being accessible by other functions. However, I can't access it from all functions for some reason. Here's the relevant part of the code:

Code:

struct FILELIST{
	char filename[255];
};

struct	FILELIST *filelist;

void load_file_list(char *filename, FILELIST *filelist){ //this function works as expected
	
	FILE *handle;
	char filename_new[255];
	unsigned long n=0;

	filelist = (FILELIST*)malloc(sizeof(FILELIST)); //allocate mem for first filename
	
	while(1){
			
		sprintf(filename_new,"%s%06lu.jpg",filename,n);

		if(handle = fopen(filename_new, "rb")){
			fclose(handle);
			filelist = ((FILELIST*)realloc(filelist, sizeof(FILELIST)*(n+1))); //add more memory
			
			strcpy(filelist[n].filename,filename_new); //copy new filename to struct
			printf("Filename is %s\n",filelist[n].filename); //this works OK

		}else{
			printf("No more files\n");
			break;
		}
		n++;
	}
}

void print_filename(void){ //this doesn't work
	printf("Filename: %s\n",filelist[0].filename);
}
