How to extract a word between , and =?

Question

Supposing I had a word:

char[1000]={"ALGUMA COISA,ALGO=TESTE,FIM"};

The word before = and = itself are optional in the sentence;

How do I store the SOMETHING word of the phrase in a variable?

The code below is what I tried, however, is not working:

#include<stdio.h>
#include<string.h>

 int main(){
char linha[1000]={"ALGUMA COISA,ALGO=TESTE,FIM"};`
char personagem[1000];
int ww=0;
int w1=0;
 int je=0;
                while(linha[w1]!='\0')
                {
                    if(linha[w1]=='=')
                    {
                        for(ww=w1;ww>0;ww--)
                        {
                            personagem[je]=linha[ww];
                            je++;
                        }
                    }
                    w1++;
                }
                personagem[je]='\0';
} 

Assuming w1 is the position found "=";
