gdb also supplies some convenience functions. These have a syntax similar to convenience variables. A convenience function can be used in an expression just like an ordinary function; however, a convenience function is implemented internally to gdb.
These functions require gdb to be configured with
Python
support.
$_memeq(
buf1,
buf2,

$_regex(
str,
regex)
Python
's
regular expression support.
$_streq(
str1,
str2)
$_strlen(
str)
gdb provides the ability to list and get help on convenience functions.
