a member function call an external function with same name

[yuanhp_china]

I define a class:
class RtServer
{
public:
RtServer();

void init();

void close();

int sockfd;
};


void RtServer::close() {
close(sockfd);
}

Here I tried to call close() which is socket interface. When
compiling, it show the error message below:
no matching function for call to `RtServer::close(int&)'

I appreciate any help.

I define a class:
class RtServer
{
public:
RtServer();

void init();

void close();

int sockfd;

};

void RtServer::close() {
close(sockfd);

The compiler looks for a matching close here - and finds the
memberfunction RtServer::close. When a matching function is found, no
further search is done - and thus the error. You need to qualify the
close call. If the close you want to call resides in the global
namespace, the correct syntax is ::close(sockfd).
