* Name: getgrnam
|
|
*
|
|
* Description:
|
|
* The getgrnam() function searches the group database for an entry with
|
|
* a matching name.
|
|
*
|
|
* Input Parameters:
|
|
* name - The group name to return a group structure for
|
|
*
|
|
* Returned Value:
|
|
* A pointer to a statically allocated group 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
|
|
* getgrnam(). If getgrnam() returns a null pointer and errno is set to
|
|
* non-zero, an error occurred.
