示例1: snprintf
void
append_uint32(string_buffer& buf, uint32_t v)
{
char *const wp = buf.make_space(64);
const int len = snprintf(wp, 64, "%lu", static_cast<unsigned long>(v));
if (len > 0) {
buf.space_wrote(len);
}
}示例2: read
int
hstcpcli::read_more()
{
const size_t block_size = 4096; // FIXME
char *const wp = readbuf.make_space(block_size);
const ssize_t rlen = read(fd.get(), wp, block_size);
if (rlen <= 0) {
if (rlen < 0) {
error_str = "read: failed";
} else {
error_str = "read: eof";
}
return rlen;
}
readbuf.space_wrote(rlen);
return rlen;
}示例3: while
