JAS_ATTRIBUTE_PURE const JAS_EXPORT jas_taginfo_t* jas_taginfo_nonull | ( | const jas_taginfo_t * | taginfo | ) |
Ensure a nonnull taginfo pointer.
This function returns a pointer to the specified taginfo object if it exists (i.e., the pointer is nonnull); otherwise, a pointer to a dummy object is returned. This is useful in some situations to avoid checking for a null pointer.
JAS_ATTRIBUTE_PURE const JAS_EXPORT jas_taginfo_t* jas_taginfos_lookup | ( | const jas_taginfo_t * | taginfos, |
const char * | name | ||
) |
Lookup a tag by name.
JAS_EXPORT jas_tvparser_t* jas_tvparser_create | ( | const char * | s | ) |
Create a tag-value parser for the specified string.
JAS_EXPORT void jas_tvparser_destroy | ( | jas_tvparser_t * | tvparser | ) |
Destroy a tag-value parser.
JAS_ATTRIBUTE_PURE const JAS_EXPORT char* jas_tvparser_gettag | ( | const jas_tvparser_t * | tvparser | ) |
Get the tag name for the current tag-value pair.
JAS_ATTRIBUTE_PURE const JAS_EXPORT char* jas_tvparser_getval | ( | const jas_tvparser_t * | tvparser | ) |
Get the value for the current tag-value pair.
JAS_EXPORT int jas_tvparser_next | ( | jas_tvparser_t * | tvparser | ) |
Get the next tag-value pair.
