C++ (Cpp) StringChunk_Free Examples

Example #1

File: main.c Project: 1way/dnsforwarder

void Probe(int Threshold)
{
	static const char *Servers[] = {

	};

	int	Pass = 0;

	StringList	l;

	StringChunk	s;

	StringList_Init(&l, NULL, ',');

Example #2

File: gfwlist.c Project: 0rt/dnsforwarder

DONE:
