Function Documentation

struct wpabuf* wpabuf_alloc ( size_t  len  )  [read]

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

Definition at line 118 of file wpabuf.c.

struct wpabuf* wpabuf_alloc_copy ( const void *  data,
size_t  len 
) [read]

Definition at line 163 of file wpabuf.c.

struct wpabuf* wpabuf_alloc_ext_data ( u8 data,
size_t  len 
) [read]

Definition at line 139 of file wpabuf.c.

struct wpabuf* wpabuf_concat ( struct wpabuf a,
struct wpabuf b 
) [read]

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.

static const u8* wpabuf_head_u8 ( const struct wpabuf buf  )  [inline, static]

Definition at line 86 of file wpabuf.h.

static size_t wpabuf_len ( const struct wpabuf buf  )  [inline, static]

wpabuf_len - Get the current length of a wpabuf buffer data : wpabuf buffer Returns: Currently used length of the buffer

Definition at line 59 of file wpabuf.h.

static void* wpabuf_mhead ( struct wpabuf buf  )  [inline, static]

wpabuf_mhead - Get modifiable pointer to the head of the buffer data : wpabuf buffer Returns: Pointer to the head of the buffer data

size_t  len 
) [inline, static]

Definition at line 151 of file wpabuf.h.

void static size_t wpabuf_size ( const struct wpabuf buf  )  [inline, static]

Definition at line 49 of file wpabuf.h.

static size_t wpabuf_tailroom ( const struct wpabuf buf  )  [inline, static]

wpabuf_tailroom - Get size of available tail room in the end of the buffer : wpabuf buffer Returns: Tail room (in bytes) of available space in the end of the buffer

Definition at line 69 of file wpabuf.h.

struct wpabuf* wpabuf_zeropad ( struct wpabuf buf,
size_t  len 
) [read]

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.
