Attributes are ignored. The functions with n as the last argument return a string at most n characters long. Return Value: Upon successful completion, innstr(), mvinnstr(), mvwinnstr() and winnstr() return the number of characters actually read into the string; instr(), mvinstr(), mvwinstr() and winstr() return OK. Otherwise, all these functions return ERR.
