C++ (Cpp) sandbox_file_read Beispiele

Beispiel #1

static size_t read_file_to_memory(const char * filename, char ** buffer)
{
	size_t len;
	char * buf;
	int fd;

	if(!filename || !buffer)
		return 0;

	if(sandbox_file_exist(filename) != 0)
		return 0;

	fd = sandbox_file_open(filename);
	if(fd <= 0)
		return 0;

	len = sandbox_file_length(fd);
	if(len <= 0)
		return 0;

	buf = malloc(len + 1);
	if(!buf)
		return 0;
	memset(buf, 0, len + 1);

	sandbox_file_seek(fd, 0);
	sandbox_file_read(fd, buf, len);
	sandbox_file_close(fd);

	*buffer = buf;
	return len;
}
