The method_getgrnam Interface
struct group *method_getgrnam (void *handlep, const char *group);
The handlep parameter is a handle to the load module opened with the method_open interface. The group parameter points to the requested group.
method_getgrnam retrieves group account information given the group name. The group account information consists of the group name, identifier, and complete member list.
method_getgrnam is called as a result of calling the getgrnam subroutine. This interface may also be called if method_getentry is not defined.
method_getgrnam returns a pointer to the group's group file structure on success. On failure a NULL pointer is returned.
