BCHECK(1)BCHECK(1)NAMEbcheck - batch utility for Runtime Checking (RTC)
SYNOPSISbcheck [ -access | -all | -leaks | -memuse ] [ -o logfile ] [ -q ] [ -s
script ] program [ args ]
DESCRIPTIONbcheck , a batch interface to dbx's Runtime Checking (RTC), is a shell
script which runs the program under dbx, with any specified args. The
RTC error output is placed in the specified logfile, or the default
file program.errs. If this file already exists, its contents are over‐
written. Although bcheck can perform memory leak checking, memory
access checking, memory use checking or all three, the default is to
perform leak checking only.
Before running bcheck on a system running the Linux OS, you must set
the _DBX_EXEC_32 environment variable.
OPTIONS-access
Perform memory access checking.
-all Perform memory access and memory leak checking.
-leaks Perform memory leak checking only. (Default)
-memuse
Perform memory use checking, which includes memory leaks check‐
ing.
-o logfile
Place the error output in logfile. or the default file pro‐
gram.errs.
-q Make bcheck completely quiet, and return with the same exit sta‐
tus as the 'program'. Useful when you want to use bcheck in
scripts, makefiles, and such.
-s script
Read in the dbx commands contained in script before execution.
Using commands like suppress and dbxenv , you can tailor the
error output of bcheck.
EXAMPLES
