35 /* --- @dspool_create@ --- *
37 * Arguments: @dspool *p@ = address of pool to create
38 * @size_t isz@ = initial size of new strings
42 * Use: Initializes a dynamic string pool.
45 void dspool_create(dspool *p, size_t isz)
51 /* --- @dspool_destroy@ --- *
53 * Arguments: @dspool *p@ = pool to destroy
57 * Use: Releases all of the strings left in the pool. Any strings
58 * not put back into the pool aren't freed. However, the pool
59 * is still valid, and the active strings can be put back and

75 /* --- @dspool_get@ --- *
77 * Arguments: @dspool *p@ = pointer to a string pool
79 * Returns: Pointer to a dynamic string.
81 * Use: Fetches a string from the pool. The string has space for at
82 * least @isz@ characters (where @isz@ is the size passed to
83 * @dspool_create@ for the pool).

95 * Use: Releases a dynamic string back into a string pool. It
96 * doesn't have to be the same pool the string actually came
97 * from, although it does have to have come from some string
