Function Documentation

void ASN1_MemExit

(

void

)

int ASN1_MemInit

(

void

)

fpa1_syntaxList* fpa1_delFirstItem

(

fpa1_syntaxList *

firstComp

)

cleans up a tree of fpa1_syntaxList items. Doesn't actually delete the memory used by the structures since they are freed as a block on parser exit (using fpa1_deleteEntireList() ).

Parameters

firstComp

list item to be deleted

Returns

fpa1_syntaxList*

int fpa1_delList

(

fpa1_syntaxList *

firstComp

)

Recursively clean up a tree of fpa1_syntaxItems We don't need to actually delete the structures as that is done by the final call to fpa1_deleteEntireList() on return of the parser.

Parameters

firstComp

list item to be deleted

Returns

int

int fpa1_freeUnusedData

(

void

)

Note: This function deletes all remaining strings within the list (as only unused strings will get this far).

Returns

int

fpa1_syntaxList* fpa1_getTagItem

(

void

)

Gets the next syntaxItem from the current syntaxBlock. Creates a new syntaxblock if necessary. fpa1_syntaxBlockInit() MUST be have been called before calling this function.

Returns

*fpa1_syntaxList
