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

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

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