Manual page for SETGROUPS(2)
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:
- [EPERM]
-
The caller is not the super-user.
- [EFAULT]
-
The address specified for gidset is outside the process
address space.
SEE ALSO
getgroups(2), initgroups(3X)
BUGS
The
gidset
array should be of type
gid_t,
but remains integer for compatibility with earlier systems.
