Hi Programmers,

I'm begginer in programming and in C/C++ ... :-)
I was looking for my help (GNU) in DEV-C++ and i want use a function that
need pwd.h ... i put it #include <pwd.h>  ...but the compiler spoke me that
it doesen't exist...i i was found and realment doesen't exist in my HardDisk
... :-/
Do you know where i can get ??
O better where i can get "several LIBS utils" ?? Until GNU libs ... for
C/C++ ... :-)
Example ... exist "netdb.h" or other libs used in C for linux, exist this
libs to win ??
Where i can get it thinks ?? :-))

I was looking for help and ...is of this kind:

The help is:

You can search the system user database for information about a specific
user using getpwuid or getpwnam.  These functions are declared in pwd.h.

Function: struct passwd * getpwuid (uid_t uid)

This function returns a pointer to a statically-allocated structure
containing information about the user whose user ID is uid.  This structure
may be overwritten on subsequent calls to getpwuid.

A null pointer value indicates there is no user in the data base with user
ID uid.

Function: int getpwuid_r (uid_t uid, struct passwd *result_buf, char *
buffer, size_t buflen, struct passwd **result)

This function is similar to getpwuid in that is returns information about
the user whose user ID is uid.  But the result is not placed in a static
buffer.  Instead the user supplied structure pointed to by result_buf is
filled with the information.  The first buflen bytes of the additional
buffer pointed to by buffer are used to contain additional information,
normally strings which are pointed to by the elements of the result
structure.

In pwd.h help:

Data Type: struct passwd

The passwd data structure is used to hold information about entries in the
system user data base.  It has at least the following members:

char *pw_name

The user's login name.


uid_t pw_uid

The user ID number.

Based in it, How to need i do to get a ID of user ??
Please give me a real example...kind ... how to get the ID of user and print
on the screen with printf ??

Thkz for all
Best Regards
