Hi,
I am making a seteuid() call to impersonate user "shweta".
Then I create a file. When I do ls -l on the file, it shows the owner as
"vishalj" which was the user before doing impersonation.
-rw-rw-rw- 1 vishalj mkgroup 0 Mar 20 12:50 shweta
Is this expected behaviour in cygwin?
I am attaching the code snippet-
#include <windows.h>
#include <sys/cygwin.h>
#include <stdio.h>
#include <pwd.h>
int main(int argc, char *argv[]){
HANDLE token = INVALID_HANDLE_VALUE;
struct passwd *pw = NULL;
FILE *fp = NULL;
pw = getpwnam("shweta");
token = cygwin_logon_user(pw, "shweta");
if(token == INVALID_HANDLE_VALUE){
printf("Login failed\n");
}
cygwin_set_impersonation_token(token);
seteuid(pw->pw_uid);
fp = fopen("shweta", "w");
if(fp == NULL){
printf("could not open file for writing\n");
}
fclose(fp);
}
Thanks,
Vishal
