acconfig.h

用来监视网络通信数据的源代码和应用程序,方便网络程序底层开发.

/* Long story short: aclocal.m4 depends on autoconf 2.13
 * implementation details wrt "const"; newer versions
 * have different implementation details so for now we
 * put "const" here.  This may cause duplicate definitions
 * in config.h but that should be OK since they're the same.
