I have a very big C programming project that uses thousands of struct variables with this naming convention: specificstruct->x = specificstruct->y + specificstruct->z I want to do some heavy refactoring, namely converting most of these struct members to arrays. The code above would look like this: specificstruct->x[i] = specificstruct...
I need to know if it's possible to use a tool like ctags or cscope to find all the usages of a function but filter the results depending on the value of one of its parameters. For example, let's assume we have a function void foo(int a, int b) that is used a thousand times along all the source tree and I need to check if it's being call...
I want to write a semantic patch for coccinelle, so that it will add if (ptr == NULL) ... checks after calls to malloc where they are missing. Let's say I have the following input source code: #include <stdio.h> #include <stdlib.h> #include <string.h> // memory leaks ignored static void OK_simple(void) { char *ptr; ptr = malloc(100...
What is the correct type to use for declaring a metavariable that possibly could match either variables or members in a struct? Take for instance the following example source code: #include <stdio.h> #include <stdlib.h> struct some_struct { int i; char *s; }; void test(void) { struct some_struct *ptr; ...
