Invalid use of const pointer?

[Joe Filion]

Hello,

 

While examining the source code for make, I see something suspicious with a const pointer.

 

Line 3094 of read.c is:

 

char *userend = strchr (name + 1, '/');

 

The name parameter is a const pointer, so the overloaded version of strchr that takes a const pointer as the first parameter should also return a const pointer. But userend is not a const pointer and is used to modify the string later in the code. I’m a bit surprised the compiler allows this and I realize this could just be a misunderstanding of something on my part. Does anyone else find this construct suspicious?

 

Thanks,

Joe
