char* qunit_findNext

struct QunitSIConversion* QunitAccumulateSIConversion

(

struct QunitSIConversion *

SIc

)

[read]

Accumulate base unit counts in SIConversion from list of unit entries, and remove any unit entries with exponent zero from list.

qunit structure accumulating routines

If new_entry is an SI_unit, look for an existing entry for this unit and accumulate the exponent if found, then free the new_entry. If new_entry is an SI_unit with no existing entry, or if it is a text entry, append it to the existing list (and don't free it!)

qunit catalogue routines

Inits catalogue of recognized SI units and their properties

struct QunitUnitDescription* QunitLookupCatalogueDescription

(

const char *

test_string

)

[read]

Lookup a unit in the catalogue by symbol or name and

return a pointer to its description, or NULL if not found.

First try for an exact case-sensitive match of unit symbol

If symbol was not matched, try for case-insensitive name match. Names are stored lowercase as per SI standard, so can do this by testing for an exact match of a lowercase copy of test_string.

void QunitPrintCatalogueDescription

(

const struct QunitUnitDescription *

descrip

)

Print qunit catalogue description of an SI unit
