[−][src]Enum coreutils_core::os::group::Error
Enum that holds possible errors while creating Group
type.
Variants
Happens when getgrgid_r
, getgrnam_r
or getgrouplist
fails.
It holds the the function that was used and a error code of the function return.
Happens when the pointer to the .gr_name
is NULL.
Happens when the pointer to the .gr_passwd
is NULL.
Happens when the pointer of group
primitive is NULL.
This can happen even if getgrgid_r
or getgrnam_r
return 0.
Io(IoError)
Happens when calling getgroups
or getgrouplist
C function.
Happens when creating a Passwd
fails.
