cc [ flag ... ] file... -llgrp [ library ... ] #include <sys/lgrp_user.h> int lgrp_nlgrps(lgrp_cookie_t cookie);
The lgrp_nlgrps() function takes a cookie representing a snapshot of the lgroup hierarchy obtained from lgrp_init(3LGRP). It returns the number of lgroups in the hierarchy where the number is always at least one.
Upon successful completion, lgrp_nlgrps() returns the number of lgroups in the system. Otherwise, it returns −1 and sets errno to indicate the error.
The lgrp_nlgrps() function will fail if:
EINVAL
