#include <pwd.h> struct qplg_passwd *QlgGetpwuid(uid_t uid);Service Program Name: QSYPAPI
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).
The struct qplg_passwd, which is defined in the pwd.h header file, has the following elements:
char * | pw_name | User name |
uid_t | pw_uid | User ID |
uid_t | pw_gid | Group ID |
Qlg_Path_Name_T* | pw_dir | Initial working directory |
char * | pw_shell | Initial user program |
See getpwuid()--Get User Information for User ID for more on the parameter.
*READ authority is required to the user profile associated with the UID.
Note: Adopted authority is not used.
If QlgGetpwuid() is not successful, errno usually indicates one of the following errors. Under some conditions, errno could indicate an error other than those listed here.
Error condition | Additional information |
---|---|
[EAGAIN] |
The user profile associated with the uid is currently locked by another process. |
[EC2] |
Detected pointer that is not valid. |
[EINVAL] |
Value is not valid. Check the job log for messages. |
[ENOENT] |
The user profile associated with UID was not found. |
[ENOMEM] |
The user profile associated with the UID has exceeded its storage limit or is unable to allocate memory. |
[ENOSPC] |
Machine storage limit exceeded. |
[EPERM] |
The calling job does not have *READ authority to the user profile associated with the UID. |
[EUNKNOWN] |
Unknown system state. Check the job log for a CPF9872 message. If there is no message, verify that the home directory field in the user profile can be displayed. |
Th path name is returned in the default IFS UNICODE CCSID

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
