c++ - 如何在 gdb 中打印长字符串的完整值？

Question

我想在 GDB 中打印 C 字符串的完整长度。默认情况下它是缩写的，如何强制 GDB 打印整个字符串？

Answer 1

set print elements 0

From the GDB manual :

set print elements number-of-elements

Set a limit on how many elements of an array GDB will print. 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. When GDB starts, this limit is set to 200. Setting number-of-elements to zero means that the printing is unlimited.
