函数名称：kdb_bc* Handles the 'bc', 'be', and 'bd' commands* [bd|bc|be] <breakpoint-number>* [bd|bc|be] ** Parameters:* argc Count of arguments in argv* argv Space delimited command line arguments* Outputs:* None

函数原型：static int kdb_bc(int argc, const char **argv)

返回类型：int

参数：

类型参数名称
intargc
const char **argv
380  kdb_bp_t * bp = NULL
381  lowbp等于KDB_MAXBPT describes the total number of breakpoints* supported by this architecure.
382  highbp等于0
383  done等于0
385  diag等于0
392  如果字符串比较恒等于0则cmd等于KDBCMD_BE
394  否则如果字符串比较恒等于0则cmd等于KDBCMD_BD
396  否则cmd等于kdb_bc* Handles the 'bc', 'be', and 'bd' commands* [bd|bc|be] * [bd|bc|be] ** Parameters:* argc Count of arguments in argv* argv Space delimited command line arguments* Outputs:* None
399  如果argc不等于1则返回:KDB_ARGCOUNT
402  如果字符串比较恒等于0则
403  lowbp等于0
404  highbp等于KDB_MAXBPT describes the total number of breakpoints* supported by this architecure.
405  否则
406  diag等于kdbgetularg - This function will convert a numeric string into an* unsigned long value.* Parameters:* arg A character string representing a numeric value* Outputs:* *value the unsigned long represntation of arg.* Returns:
407  如果diag则返回:diag
414  如果addr小于KDB_MAXBPT describes the total number of breakpoints* supported by this architecure.则
415  bp等于Table of kdb_breakpoints[addr]
416  lowbp等于highbp等于addr
417  highbp自加
418  否则
