Yes, trivial:

#include <extractor.h>

char * getMime(const char *  filename) {
 EXTRACTOR_ExtractorList * ex = EXTRACTOR_loadDefaultLibraries();
 EXTRACTOR_KeywordList * kl = EXTRACTOR_getKeywords(ex, filename);
 char * mimetype = strdup(EXTRACTOR_extractLast(EXTRACTOR_MIMETYPE, kl);
 EXTRACTOR_freeKeywords(kl);
 EXTRACTOR_removeAll(ex);
 return mimetype;
}
