Added stubbed implementations of getpwuid, getpwuid_r, getpwnam, and getpwnam_r. These functions are essentially stubs pretending that NuttX supported users and that the only configured user in the system was 'root' with uid 0. The intend is not to provide meaningful new features, but to ease porting of foreign source code to NuttX.

* Name: getpwnam
|
|
*
|
|
* Description:
|
|
* The getpwnam() function searches the user database for an entry with a
|
|
* matching name.
|
|
*
|
|
* Input Parameters:
|
|
* name - The user name to return a passwd structure for.
|
|
*
|
|
* Returned Value:
|
|
* A pointer to a statically allocated passwd structure, or NULL if no
|
|
* matching entry is found or an error occurs. Applications wishing to
|
|
* check for error situations should set errno to 0 before calling
|
|
* getpwnam(). If getpwnam() returns a null pointer and errno is set to
|
|
* non-zero, an error occurred.
