Hi All, I'm getting "warning: implicit declaration of function ‘strdup’". The man pages tell me to include string.h. In string.h (which is included): #if defined __USE_SVID || defined __USE_BSD || defined __USE_XOPEN_EXTENDED /* Duplicate S, returning an identical malloc'd string. */ extern char *strdup (__const char *__s) __THROW __attribute_malloc__ __nonnull ((1)); #endif I feel like I'm missing something since strdup is guarded with library/operating system macros. Can anyone point out my mistake? Or should I just declare it extern myself? Jeff
