I want to print the full length of a C-string in GDB. By default it's being abbreviated, how do I force GDB to print the whole string?

In GDB, when you display the value of a C-string or a C++ std::string, it might get abbreviated if it's long. To print the full value of a long string in GDB, you can use the set print elements …

Format If specified, allows overriding the output format used by the command. Valid format specifiers are: o - octal x - hexadecimal u - unsigned decimal t - binary f - floating point a - …

In GDB, generally to print the value of the variable ,we use print or just p. But for the strings or arrays of large size , it wont print whole string or array.

With a pretty-printer for std::string only the contents are printed: (gdb) print s $2 = "abcd"

If GDB is printing a large array, it stops printing after it has printed the number of elements set by the set print elements command. This limit also applies to the display of strings.

Is there some "default function" to print an object like a string on the GDB when we are debugging C++ applications? Something like: toString(); Or my class have to implement something like that?

(gdb) set print elements 0 (gdb) show print elements Limit on string chars or array elements to print is unlimited.
