#include <ufas.h> stat = u_del( fp[, keyinfo] ); stat = u_del( fp, keynum, keyptr );
"u_del" deletes one record from the named file. If the file is open for sequential access, the optional key arguments should be omitted; in this case, the last record obtained by calling "u_gxt" is deleted. Otherwise, the record identified by the given key is deleted.
Since "keynum" must always be zero, it may be omitted, and the routine will determine the type of the second argument according to the file organization. The second calling sequence is actually only provided for the sake of type matching across calls.
