Enter Location dialog box

In this section:

The Enter Location dialog box is available from the breakpoints dialog box, either when you set a new breakpoint or when you edit a breakpoint.

Use the Enter Location dialog box to specify the location of the breakpoint.

Note

This dialog box looks different depending on the Type you select.

Type

Selects the type of location to be used for the breakpoint, choose between:

Expression

A C-SPY expression, whose value evaluates to a valid code or data location.

A code location, for example the function main, is typically used for code breakpoints.

A data location is the name of a variable and is typically used for data breakpoints. For example, my_var refers to the location of the variable my_var, and arr[3] refers to the location of the fourth element of the array arr. For static variables declared with the same name in several functions, use the syntax my_func::my_static_variable to refer to a specific variable.

For more information about C-SPY expressions, see C-SPY expressions.

Absolute address

An absolute location on the form zone:hexaddress or simply hexaddress (for example Memory:0x42). zone refers to C-SPY memory zones and specifies in which memory the address belongs, see C-SPY memory zones.

Source location

A location in your C source code using the syntax: {filename}.row.column.

filename specifies the filename and full path.

row specifies the row in which you want the breakpoint.

column specifies the column in which you want the breakpoint.

For example, {C:\src\prog.c}.22.3 sets a breakpoint on the third character position on row 22 in the source file prog.c. Note that in quoted form, for example in a C-SPY macro, you must instead write {C:\\src\\prog.c}.22.3.

Note that the Source location type is usually meaningful only for code locations in code breakpoints. Depending on the C-SPY driver you are using, Source location might not be available for data and immediate breakpoints.
