wpabuf_alloc - Allocate a wpabuf of the given size : Length for the allocated buffer Returns: Buffer to the allocated wpabuf or NULL on failure

wpabuf_concat - Concatenate two buffers into a newly allocated one : First buffer : Second buffer Returns: wpabuf with concatenated a + b data or NULL on failure
Both buffers a and b will be freed regardless of the return value. Input buffers can be NULL which is interpreted as an empty buffer.

wpabuf_zeropad - Pad buffer with 0x00 octets (prefix) to specified length : Buffer to be padded : Length for the padded buffer Returns: wpabuf padded to len octets or NULL on failure
If buf is longer than len octets or of same size, it will be returned as-is. Otherwise a new buffer is allocated and prefixed with 0x00 octets followed by the source data. The source buffer will be freed on error, i.e., caller will only be responsible on freeing the returned buffer. If buf is NULL, NULL will be returned.
