silc_buffer_pull_tail

SYNOPSIS

    static inline
    unsigned char *silc_buffer_pull_tail(SilcBuffer sb, SilcUInt32 len);

DESCRIPTION

Pulls current tail section towards end. Length of the current valid data area is also incremented. Returns a pointer to the data area before pulling. Returns NULL if the pull would lead to buffer overflow.

EXAMPLE

    ---------------------------------
    | head  | data       | tail     |
    ---------------------------------
                         ^
                         Pulls the start of the tail section.

    ---------------------------------
    | head  | data           | tail |
    ---------------------------------
                         ^

    silc_buffer_pull_tail(sb, 23);
