 #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 information about the parameter.

Authorities

*READ authority is required to the user profile associated with the UID.

Note: Adopted authority is not used.

Return Value

value

QlgGetpwuid() was successful. The return value points to static data that is overwritten on each call to this function. This static storage area is also used by the QlgGetpwnam() function.

NULL pointer

QlgGetpwuid() was not successful. The errno global variable is set to indicate the error.

#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
