* Name: getpwnam_r
|
|
*
|
|
* Description:
|
|
* The getpwnam_r() function searches the user database for an entry with a
|
|
* matching name and stores the retrieved passwd structure in the space
|
|
* pointed to by pwd.
|
|
*
|
|
* Input Parameters:
|
|
* name - The name to return a passwd structure for.
|
|
* pwd - Pointer to the space to store the retrieved passwd structure in.
|
|
* buf - The string fields pointed to by the passwd struct are stored here.
|
|
* buflen - The length of buf in bytes.
|
|
* result - Pointer to the resulting passwd struct, or NULL in case of
|
|
* fail.
|
|
*
|
|
* Returned Value:
|
|
* On success getpwnam_r returns 0 and sets *result to pwd. If no match
|
|
* is found, 0 is returned and *result is set to NULL. In case of failure
|
|
* an error number is returned.
