7.21.2.1 Non Data Type Specific Decq Functions

• - void ‘q_class’(decq q);

  deletes the first element in the q sequence

• - void ‘q_clear’(decq q);

  empties the q sequence

• - void ‘q_copy’(decq q, decq v);

  empties the q sequence and copies the content of the v sequence in q

• - integer ‘q_length’(decq q);

  is the length (i.e. number of items) of the q sequence

• - void ‘q_new’(decq &q);

  sets the q sequence as a new sequence (same as ‘q_clear’ if q is not linked multiple times, otherwise creates a new sequence and sets q as a reference to the new sequence)

  The function is generated on request only.

  See Decq Library Generation Flags.

• - void ‘q_reel’(decq q);

  moves the first element in the q sequence in the last position

• - void ‘q_roll’(decq q);

  moves the last element in the q sequence in the first position

• - decq ‘q_set’(decq &q, decq v);

  is v, sets the q sequence as a reference of the v sequence

  The function is generated on request only.

  See Decq Library Generation Flags.

• - void ‘q_short’(decq q);

  deletes the last element in the q sequence

• - void ‘q_swap’(decq q, decq v);

  exchanges the content of the q and v sequences
