The -data-evaluate-expression command

Synopsis

-data-evaluate-expression expr

Evaluate expr as an expression. The expression could contain an inferior function call.
The function call will execute synchronously. If the expression contains spaces, it must
be enclosed in double quotes.

GDB command

The corresponding GDB commands are 'print', 'output', and 'call'. In gdbtk only,
there is a corresponding 'gdb_eval' command.

Example

In the following example, the numbers that precede the commands are the tokens
described in

“GDB/MI Command Syntax” (page 307)

. Notice how GDB/MI returns the

same tokens in its output.

211-data-evaluate-expression A
211^done,value="1"
(gdb)
311-data-evaluate-expression &A
311^done,value="0xefffeb7c"
(gdb)
411-data-evaluate-expression A+3
411^done,value="4"
(gdb)
511-data-evaluate-expression "A + 3"
511^done,value="4"
