Thread: u_short header?

I am trying to cast a variable using the "ushort" type but am receiving an error of "u_short undeclared: first use of this function". I looked online and saw that it resides in the types.h header but when I try to include this header I receive another error of this header doesn't exist. Is this the correct header which I am trying to include or is there a way to get this header installed so I can make this conversion. Thanks!

Code:

#include <types.h>

.....

sin.sin_port = htons((u_short)port);




$make
$myTCP.c:7:60: error: types.h: No such file or directory
$myTCP.c: In function ‘myTCPconnect’:
$myTCP.c:48: error: ‘u_short’ undeclared (first use in this function)

My check of sys/types.h online didn't reveal either a "ushort" or a "u_short". (Notice that it would be sys/types.h, not types.h, and that would only work if you actually have it, as it's not a standard header.) I suppose you can check your own types.h, if you have one, and see if there is a "ushort" or a "u_short" defined.

I was looking at the header online and I believe that it just assigns "unsigned short" to u_short. After replace the (u_short) with the (unsigned short) everything appears to be working fine. Thank you for your help though.

1. #include <stdint.h>
2. sys/types.h - as name suggests is system specific (normally this might come with the kernel as it is on Linux, glibc uses particular version of kernel headers which provide sys/types.h), might be u_short on one system, ushort on other system, and perhaps unsigned_short on yet another one, only stdint.h provides uniform typedefs
3. in stdint you have uint16_t... analogically for other types
