getpwuid() -- General Function (libc)

Get password file information, by id
#include <pwd.h>
struct passwd *getpwuid(uid)
int uid;

The COHERENT  system has  five routines  that search the  file /etc/passwd,
which contains  information about every  user of the  system.  The returned
structure passwd is defined in  the header file pwd.h. For more information
on this structure, see pwd.h.

getpwuid() attempts  to find the  first entry with  a numerical user  id of
uid.

Example

For an example of this function, see the entry for getpwent().

Diagnostics

getpwuid() returns NULL for any error or on end of file.

Notes

All structures  and information  returned are  in static areas  internal to
getpwuid(). Therefore,  information from a previous  call is overwritten by
each subsequent call.
