Input: lstack item to be added to the lstack Return: 0 if OK; 1 on error.
L_STACK* lstackCreate | ( | l_int32 | nalloc | ) |
Input: nalloc (initial ptr array size; use 0 for default) Return: lstack, or null on error
void lstackDestroy | ( | L_STACK ** | plstack, |
l_int32 | freeflag | ||
) |
Input: &lstack (<to be="" nulled>="">) freeflag (TRUE to free each remaining struct in the array) Return: void
Notes: (1) If freeflag is TRUE, frees each struct in the array. (2) If freeflag is FALSE but there are elements on the array, gives a warning and destroys the array. This will cause a memory leak of all the items that were on the lstack. So if the items require their own destroy function, they must be destroyed before the lstack. (3) To destroy the lstack, we destroy the ptr array, then the lstack, and then null the contents of the input ptr.
l_int32 lstackExtendArray | ( | L_STACK * | lstack | ) |
Input: lstack Return: 0 if OK; 1 on error
l_int32 lstackGetCount | ( | L_STACK * | lstack | ) |
Input: lstack Return: count, or 0 on error
l_int32 lstackPrint | ( | FILE * | fp, |
L_STACK * | lstack | ||
) |
Input: stream lstack Return: 0 if OK; 1 on error
void* lstackRemove | ( | L_STACK * | lstack | ) |
Input: lstack Return: ptr to item popped from the top of the lstack, or null if the lstack is empty or on error
