help me please (VC/UNIX GNU C help)

[YYboy]

i want to develop a C program in Visual C IDE which can also run in
UNIX without any source code modification after recompile it , so i only used VC lib functions which also active in UNIX, i want to get a standard win32 help file of UNIX C library, so i can attach it to VC IDE as the extend help, for some reason, our unix don't support XWindow, so the C help in Unix is very troublesome to be used, we can use the TC or BorlandC
help file but we are worried that some C function offered in BorlandC
are not supported in VC

help me please

你的问题实在是目前没有好的解决方案！
完全的可移植几乎不可能！

[opkj]

bc,tc和gnu c之间的移植是非常方便的。vc同gnu c简直是水火不相融。

[Redspider]

ANSI C是通用的，只要你不用MFC以及SDK，只用ANSI C里的RUNTIME LIB就应该可以。

用
#define
#ifdef
#else
#endif

隔离平台相关代码，跨平台软件都是这么做的
