char pointer to 2D char array

Andrej Prs #1 / 4	char pointer to 2D char array Hello, everyone! Could someone please tell me if this declaration is OK: char entry_string[4][255]; char entry[4] = {entry_string[0], entry_string[1], entry_string[2], entry_string[3]}; Splint warns me about this: phoebe_gui_accessories.c:500:20: Initialized storage entry_string[0] not completely defined ((entry_string[0]) is undefined): entry[0] = entry_string[0] Storage derivable from a parameter, return value or global is not need not be defined. (Use -compdef to inhibit warning) And alike for the [1], [2] and [3]. Is it true that I cannot do it this way? I use sprintf later to write to these pointers, e.g. sprintf (entry[0], "String1"); etc. Thanks for your time, Andrej

(Use -compdef to inhibit warning) Splint is being an idiot. The contents of entry_string[0] have nothing whatever to do with initialising a char * to point to it. You may or may not be able to get around this using &entrystring[0][0], but frankly I doubt it. Richard
