/****************************************************************************** FILE: DELBLK.C USAGE: DELBLK This program deletes a block, profile, or sequence of profiles from a CODAS database. It provides the user with four options: 1. Delete block range 2. Delete block-profile range 3. Delete time range 4. Exit program Hui Zhu 87-03-10 89/05/23 - JR - Added compiler-switchable modifications to permit use with CODAS3. Improved error-handling (will abort on error). Modified option to delete range of block-profiles to handle ranges that cross block boundaries. 91/09/11 - JR - Reduced from 6 to 4 options. Modified to 'dbmove' only if the end of the user range has not been reached (otherwise, can cause error messages when range ends exactly at database end). ******************************************************************************/ #include "geninc.h" /* YMDHMS_TIME_TYPE, DBDELPRF(), DBDELBLK(), ... */ #include "use_db.h" /* check_db*(), db*_cnf() */ #if PROTOTYPE_ALLOWED void main(int argc, char *argv[]) #else void main(argc, argv) int argc; char *argv[]; #endif { BLKPRF_INDEX_TYPE bpfrom, bpto, curr_bp; YMDHMS_TIME_TYPE timefrom, timeto, curr_time; FILE_NAME_TYPE dbname; int choice, count = 0, ier = 0; char answer = 'N'; unsigned int nt = sizeof(YMDHMS_TIME_TYPE), nbp = sizeof(BLKPRF_INDEX_TYPE); char buff[80]; if (argc < 2) { printf("\n ENTER DATABASE NAME: "); gets(dbname); } else strcpy(dbname, argv[1]); if (dbopen_cnf(1, dbname, READ_WRITE, DIR_IN_MEMORY)) return; do { printf("\n Enter one of the following numbers : \n\n"); printf(" 1.
