How to extract a word between, e =?

Assuming I have a word:

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

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

How do I store the word SOMETHING in a variable?

The code below is what I tried, but it 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]!='
#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]!='%pre%')
                {
                    if(linha[w1]=='=')
                    {
                        for(ww=w1;ww>0;ww--)
                        {
                            personagem[je]=linha[ww];
                            je++;
                        }
                    }
                    w1++;
                }
                personagem[je]='%pre%';
} 
')
                {
                    if(linha[w1]=='=')
                    {
                        for(ww=w1;ww>0;ww--)
                        {
                            personagem[je]=linha[ww];
                            je++;
                        }
                    }
                    w1++;
                }
                personagem[je]='%pre%';
} 

Assuming that w1 is the position found "=";
