Name
dev_alloc -- allocate a network device and name
Synopsis
struct net_device * dev_alloc (const char * name, int * err);
Arguments
- name
name format string
- err
error return pointer
Description
Passed a format string, eg. "ltd", it will allocate a network device
and space for the name. NULL is returned if no memory is available.
If the allocation succeeds then the name is assigned and the
device pointer returned. NULL is returned if the name allocation
failed. The cause of an error is returned as a negative errno code
in the variable err points to.
The caller must hold the dev_base or RTNL locks when doing this in
order to avoid duplicate name allocations.
