/*
** file: d_getfld.c
** purpose: routine to fill a buffer with field data from a dbiii file
** opened with d_open and accessed with d_getrec. the data from the
** record is copied into the buffer and terminated with '\0'
** usage: d = (struct DBF *)malloc(sizeof(struct DBF));
** strcpy(d->filename,"filename.dbf");
** d_open(d);
** d_getrec(d,(long)recordno);
** d_getfld(d,fieldno,buffer);
** ... use field data ...
** d_close(d);
** free(d);
** notes: compile with "tcc -c d_getfld". include this file in dbf.li
** see dbf.h for structure of DBF
** returns: field type if successful
** null if not
