910702-Linux中的vscprintf等效项? [英] 910702 - vscprintf equivalent in Linux?

问题描述

嗨 Linux下_vscprintf的等效功能是什么?
thx

解决方案

嗯，这很棘手！ :-)我一直使用 vsnprintf() [ vsnprintf() [ ^ ]

hi what''s the equivalent function for _vscprintf under Linux?
thx

解决方案

Well, this is tricky! :-) I have always used vsnprintf()[^] to do the job by specifying NULL and zero as the first two parameters. If you look at the documentation and check out what it says about the return value you will see that this is perfectly valid usage of the function!

EDIT: The same function in the VC++ crt isn''t compatible with the linux version, the windows version returns -1 when the output needs to be truncated. See the docs: vsnprintf()[^]
