It appears that these interfaces are undocumented in the Texinfo manual. Why not just add these as functions also, e.g. as done with htons and friends in <netinet/in.h>: extern uint16_t htons (uint16_t __hostshort) __THROW __attribute__ ((__const__)); -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 6+ messages in thread
