select( ) function with socket

select( ) function with socket

[ych43]

Hi,
 I use select( ) function of socket programming on linux. After this function, 
I try to print the return value of select( ) function out. But there is no 
return value coming out, even no any error out. So I do not know what's wrong 
with this function. If I incorrectly used this function, some errors would 
come out. But no any error comes out. Can anybody help me.
 Thank in advance!
 king regards

       On success, select returns the number  of  descriptors  contained 
in the descriptor sets, which may be zero if the timeout expires before 
anything happens. Hence its possible that maybe your timeout os set to zero.
