nla_find - Find a specific attribute in a stream of attributes : head of attribute stream : length of attribute stream : type of attribute to look for
Returns the first attribute in the stream matching the specified type.
Definition at line 220 of file nlattr.c.
nla_memcmp - Compare an attribute with sized memory area : netlink attribute : memory area : size of memory area
Definition at line 288 of file nlattr.c.
nla_memcpy - Copy a netlink attribute into another memory area : where to copy to memcpy : netlink attribute to copy from : size of the destination area
Note: The number of bytes copied is limited by the length of attribute's payload. memcpy
Returns the number of bytes copied.
Definition at line 273 of file nlattr.c.
nla_parse - Parse a stream of attributes into a tb buffer : destination array with maxtype+1 elements : maximum attribute type to be expected : head of attribute stream : length of attribute stream : validation policy
Parses a stream of attributes and stores a pointer to each attribute in the tb array accessible via the attribute type. Attributes with a type exceeding maxtype will be silently ignored for backwards compatibility reasons. policy may be set to NULL if no validation is required.
Returns 0 on success or a negative error code.
Definition at line 181 of file nlattr.c.
nla_policy_len - Determin the max. length of a policy : policy to use
: number of policies
Determines the max. length of the policy. It is currently used to allocated Netlink buffers roughly the size of the actual message.
Returns 0 on success or a negative error code.
Definition at line 152 of file nlattr.c.
nla_strcmp - Compare a string attribute against a string : netlink string attribute : another string
Definition at line 304 of file nlattr.c.
nla_strlcpy - Copy string attribute payload into a sized buffer : where to copy the string to : attribute to copy the string from : size of destination buffer
Copies at most dstsize - 1 bytes into the destination buffer. The result is always a valid NUL-terminated string. Unlike strlcpy the destination buffer is always padded out.
Returns the length of the source buffer.
Definition at line 244 of file nlattr.c.
nla_validate - Validate a stream of attributes : head of attribute stream : length of attribute stream : maximum attribute type to be expected : validation policy
Validates all attributes in the specified attribute stream against the specified policy. Attributes with a type exceeding maxtype will be ignored. See documenation of struct nla_policy for more details.
Returns 0 on success or a negative error code.
