[SOLVED] [c] set supplementary groups of process

Unfortunately the setuid() function from unistd.h does not effect the supplementary group ids of the process. Is there a way to set them directly? Even better, is there a setuid() equivalent which also sets the process's supplementary gid's to match the user's?

setgroups() does it. setegid() is for the effective group id.
