#include <stdlib.h>
#include <stdio.h>
int main(void)
{
const char *homeDir = getenv("HOME");
if (homeDir)
printf("Home directory is %s\n", homeDir);
else
printf("Couldn't figure it out.\n");
return 0;
}

This should work under Linux, Unix and OS X, for Windows you need to make a slight modification.
这应该适用于 Linux、Unix 和 OS X，对于 Windows，您需要稍作修改。
#include <stdlib.h>
#include <stdio.h>
#include <pwd.h>
#include <unistd.h>
int main(void)
{
const char *homeDir = getenv("HOME");
if !homeDir {
struct passwd* pwd = getpwuid(getuid());
if (pwd)
homeDir = pwd->pw_dir;
}
printf("Home directory is %s\n", homeDir);
return 0;
}

with FSFindFolder:
使用 FSFindFolder：
UInt8 path[1024];
FSRef file;
FSFindFolder( kOnAppropriateDisk , kCurrentUserFolderType , kCreateFolder , &file );
FSRefMakePath( &file , path , sizeof(path) );
with CSCopyUserName:
使用 CSCopyUserName：
char path[1024];
CFStringRef name = CSCopyUserName( true );
CFStringRef full = CFStringCreateWithFormat( NULL , NULL , CFSTR( "/Users/%@" ) , name );
CFStringGetCString( full , path , sizeof(path) , kCFStringEncodingUTF8 );
// release strings
with NSHomeDirectory:
使用 NSHomeDirectory：
char path[1024];
CFStringGetCString( (CFStringRef)NSHomeDirectory() , path , sizeof(path) , kCFStringEncodingUTF8 );
note that the path can use UTF8 characters.
请注意，路径可以使用 UTF8 字符。
