JK> If this is a real concern, use a loop with istream::get(), that dynamically allocates a return buffer as it goes along until it reads a newline character. For best results, considering the way that most C++ run-time heaps are mannaged, reallocate the return buffer 16 bytes bigger every 16 bytes (or use a larger power of two). You must remember to destroy the buffer after use, of course. > JdeBP < ___ X MegaMail 2.10 #0: --- Maximus/2 2.02* Origin: DoNoR/2,Woking UK (44-1483-722344) (2:440/4) SEEN-BY: 105/42 620/243 711/401 409 410 413 430 807 808 809 934 955 712/407 SEEN-BY: 712/515 628 704 713/888 800/1 7877/2809 @PATH: 440/4 141/209 270/101 105/103 42 712/515 711/808 809 934 |
