myCompare23()

static int myCompare23 ( const void *  pkey, const void *  pelem  )

static

Parameters

pkey	pointer to two-character ISO639-1 language key
pelem	pointer to mISO639_2_3_pairs record

Return values

negative	iff pkey is before pelem
positive	iff pkey is after pelem
zero	iff pkey matches pelem

static

Parameters

pkey	pointer to three-character ISO639-2 language key
pelem	pointer to mBibliographicTerminologyPairs record

Return values

negative	iff pkey is before pelem
positive	iff pkey is after pelem
zero	iff pkey matches pelem

Definition at line 286 of file iso639map.cpp.

MapISO639_BibliographicToTerminology()

static const char* MapISO639_BibliographicToTerminology ( const char *  language3 )

static

map "bibliographic" language code to corresponding "terminology" language code

Parameters

language3

three-character ISO639-2 language key
