Add a function prototype using the protoize command of linux

This article mainly introduces the use of linux prototype command to add function prototype, the text is very detailed, has a certain reference value, interested friends must read!

The prototype command belongs to the gcc suite and is used to add function prototypes to C source code files to convert GNU-C code to ANSI-C code. The prototype command relies on the gcc command to scan C source code and gather information about the functions used.

Basic conversions using the customize command involve rewriting most function definitions and function declarations to specify the type of parameters.

The prototype command optionally inserts prototype declarations at the beginning of the source file so that they are available for all calls prior to the function definition. Or you can insert prototype declarations with block scopes in blocks that call undeclared functions.

Syntax format: exploit [parameters] [file]

Common parameters:

Reference Example

Add function prototypes to C source code files:

[root@linuxcool ~]# protoize test.c

Set the directory that needs conversion code:

[root@linuxcool ~]# protoize -d /root test.c

Quiet mode automatically adds function prototypes:

[root@linuxcool ~]#prototype-q test.c The above is all the content of adding function prototypes using the Linux prototype command. Thank you for reading! Hope to share the content to help everyone, more relevant knowledge, welcome to pay attention to the industry information channel!
