warning: deprecated conversion from string constant to ‘char*’?

I got this warning from the compiler:

warning: deprecated conversion from string constant to ‘char*’

when I tried to pass a string constant to a function that has a char* input argument. Something like

Quote:

myfunction("my string");

What's the correct way to do this? Thanks!

C89 introduced the const keyword. String literals are now considered const char *s. To preserve backwards compatibility, they allowed implicit conversion between string literals and char *, but it's deprecated. It's safe to say it will not be removed in the next standard though as there are still tons of libraries that do it.
