Hi Daniel, I guess we can be 100% sure of ALL platforms but it is a macro on all the ones I tested: SmartOS and Solaris 11: ``` #if !defined(_XPG4_2) || defined(__EXTENSIONS__) #define ntohll(x) (x) #define htonll(x) (x) #endif /* !_XPG4_2 || __EXTENSIONS__ */ ``` OSX: ``` #if defined(KERNEL) || (!defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)) #define ntohll(x) ((__uint64_t)(x)) #define htonll(x) ((__uint64_t)(x)) #define NTOHL(x) (x) #define NTOHS(x) (x) #define NTOHLL(x) (x) #define HTONL(x) (x) #define HTONS(x) (x) #define HTONLL(x) (x) #endif /* defined(KERNEL) || (!defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)) */ ``` --- You are receiving this because you are subscribed to this thread.

Hi Daniel, I must have not had enough coffee... testing the Solaris macros above only work on big endian machines. I've included the relevant parts of sys/byteorder.h below. Would it be acceptable to change these functions to ```_ntohll``` and ```_htonll``` to avoid the namespace conflict? The challenge with checking __OS_solaris is that this was a relatively recent addition, I think only available in Solaris 11 and the Ilumos derivatives. ``` #include <sys/isa_defs.h> #include <sys/int_types.h> #if defined(__GNUC__) && defined(_ASM_INLINES) && \ (defined(__i386) || defined(__amd64)) #include <asm/byteorder.h> #endif #ifdef __cplusplus extern "C" { #endif /* * macros for conversion between host and (internet) network byte order */ #if defined(_BIG_ENDIAN) && !defined(ntohl) && !defined(__lint) /* big-endian */ #define ntohl(x) (x) #define ntohs(x) (x) #define htonl(x) (x) #define htons(x) (x) #if !defined(_XPG4_2) || defined(__EXTENSIONS__) #define ntohll(x) (x) #define htonll(x) (x) #endif /* !_XPG4_2 || __EXTENSIONS__ */ #elif !defined(ntohl) /* little-endian */ #ifndef _IN_PORT_T #define _IN_PORT_T typedef uint16_t in_port_t; #endif #ifndef _IN_ADDR_T #define _IN_ADDR_T typedef uint32_t in_addr_t; #endif #if !defined(_XPG4_2) || defined(__EXTENSIONS__) || defined(_XPG5) extern uint32_t htonl(uint32_t); extern uint16_t htons(uint16_t); extern uint32_t ntohl(uint32_t); extern uint16_t ntohs(uint16_t); #else extern in_addr_t htonl(in_addr_t); extern in_port_t htons(in_port_t); extern in_addr_t ntohl(in_addr_t); extern in_port_t ntohs(in_port_t); #endif /* !_XPG4_2 || __EXTENSIONS__ || _XPG5 */ #if defined(_LP64) || defined(_LONGLONG_TYPE) #if !defined(_XPG4_2) || defined(__EXTENSIONS__) extern uint64_t htonll(uint64_t); extern uint64_t ntohll(uint64_t); #endif /* !_XPG4_2 || __EXTENSIONS__ */ #endif /* _LP64 || _LONGLONG_TYPE */ #endif ``` --- You are receiving this because you are subscribed to this thread.
