initgroups - initialize group access list
LIBRARY

SYNOPSIS
#include <unistd.h>

the group access list for the user specified in name. This group list is
then setup for the current process using setgroups(2). The basegid is
automatically included in the groups list. Typically this value is given
as the group number from the password file.
RETURN VALUES
The initgroups() function returns the value 0 if successful; otherwise
the value -1 is returned and the global variable errno is set to indicate
the error.
ERRORS
The initgroups() function may fail and set errno for any of the errors
specified for the library function setgroups(2). It may also return:
[ENOMEM] The initgroups() function was unable to allocate
temporary storage.
