SETGROUPS 2 ""
C 5 NAME
setgroups - set group access list
SYNOPSIS
#include <sys/param.h>setgroups(ngroups, gidset) int ngroups, *gidset;
DESCRIPTION
Setgroups sets the group access list of the current user process
according to the array
gidset . The parameter
ngroups indicates the number of entries in the array and must be no
more than NGROUPS, as defined in
< sys/param.h >. Only the super-user may set new groups.
"RETURN VALUE
A 0 value is returned on success, -1 on error, with
a error code stored in errno.
"ERRORS
The setgroups call will fail if:
15 [EPERM] The caller is not the super-user.
15 [EFAULT] The address specified for gidset is outside the process address space.
"SEE ALSO
getgroups(2), initgroups(3)
BUGS
The
gidset array should be of type
gid_t , but remains integer for compatibility with earlier systems.
