| * 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. |
