pbuf_take_at() function

Same as pbuf_take() but puts data at an offset

Syntax

err_t pbuf_take_at(struct pbuf *buf,     const void *dataptr,     u16_t len,     u16_t offset);
Implemented in pbuf.c:1239

Arguments

buf

pbuf to fill with data

dataptr

application supplied data buffer

len

length of the application supplied data buffer

offset

offset in pbuf where to copy dataptr to

Return value

ERR_OK if successful, ERR_MEM if the pbuf is not big enough
