What exactly do you want to do? I also suggest you read the community guidelines on how to make a good question.

Opa Paulo. So it is difficult to help you, edit your question and explain what you are trying to do and what mistake is happening.

You set your function with the parameter being a single character (char x) but call the function by passing an array of conta_str(str) characters, and your function does absolutely nothing with the parameter.

A possible alternative:

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

/*Função que verifica tamanho da string*/
int conta_str(char x[]){
    int i=0;
    while (x[i] != '\0')
        i++;
    if (i < 8) {
        printf("Tamanho inferior a 8 caracteres...");
        return -1;
    }
   else
        return i;
}


int main(){
    char str[40];
    int tamanho;
    gets(str);
    tamanho = conta_str(str);
    if (tamanho == -1)
        printf("Tamanho inferior a 8 caracteres...");
    else
        printf("Tamanho de %s: %d\n", str, tamanho);
    return 0;
}
