 #include <pwd.h>

 struct qplg_passwd *QlgGetpwuid(uid_t uid);   

The QlgGetpwuid() function returns a pointer to an object of type struct qplg_passwd containing an entry from the user database with a matching user ID (UID).

Parameters

UID

(Input) User ID.

The struct qplg_passwd, which is defined in the pwd.h header file, has the following elements:

See getpwuid()--Get User Information for User ID for more on the parameter.

Example

See Code disclaimer information for information pertaining to code examples.

The following example gets the user database information for the uid of 22. The user name is MYUSER. The gid is 1012. The initial working directory is /home/MYUSER. The initial user program is *LIBL/QCMD.

#include <pwd.h>

main()
{
  struct qplg_passwd *pd;

  if (NULL == (pd = QlgGetpwuid(22)))
     perror("QlgGetpwuid() error.");
  else
  {
     printf("The user name is: %s\n", pd->pw_name);
     printf("The user id   is: %u\n", pd->pw_uid);
     printf("The group id  is: %u\n", pd->pw_gid);
     printf("The initial working directory length is: %d\n",
             pd->pw_dir->Path_Length);
     printf("The initial working directory CCSID is : %d\n",
             pd->pw_dir->CCSID);
     printf("The initial user program is: %s\n", pd->pw_shell);
  }

}

Output:

  The user name is: MYUSER
  The user id   is: 22
  The group id  is: 1012
  The intial working directory length is: 24
  The intial working directory CCSID is : 13488
  The initial user program is: *LIBL/QCMD
