<h3>GETPWNAM(3)         Linux Programmer's Manual         GETPWNAM(3)
</h3>

<h3>NAME
</h3>       getpwnam, getpwuid - get password file entry

<h3>SYNOPSIS
</h3>       #include &lt;pwd.h&gt;
       #include &lt;sys/types.h&gt;

       struct passwd *getpwnam(const char * name);

       struct passwd *getpwuid(uid_t uid);

<h3>DESCRIPTION
</h3>       The  getpwnam()  function returns a pointer to a structure
       containing  the  broken  out  fields  of   a   line   from
       /etc/passwd for the entry that matches the user name name.

       The getpwuid() function returns a pointer to  a  structure
       containing   the   broken   out  fields  of  a  line  from
       /etc/passwd for the entry that matches the user uid uid.

       The passwd structure is defined in &lt;pwd.h&gt; as follows:

              struct passwd {
                      char    *pw_name;       /* user name */
                      char    *pw_passwd;     /* user password */
                      uid_t   pw_uid;         /* user id */
                      gid_t   pw_gid;         /* group id */
                      char    *pw_gecos;      /* real name */
                      char    *pw_dir;        /* home directory */
                      char    *pw_shell;      /* shell program */
              };

<h3>RETURN VALUE
</h3>       The getpwnam() and getpwuid() functions return the  passwd
       structure,  or  NULL if the matching entry is not found or
       an error occurs.

<h3>ERRORS
</h3>       ENOMEM Insufficient memory to allocate passwd structure.

<h3>FILES
