I have the struct of the lists in a header
build netbeans:
"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
"/usr/bin/make" -f nbproject/Makefile-Debug.mk dist/Debug/GNU-MacOSX/tp
mkdir -p build/Debug/GNU-MacOSX
rm -f build/Debug/GNU-MacOSX/main.o.d
gcc -c -g -MMD -MP -MF build/Debug/GNU-MacOSX/main.o.d -o build/Debug/GNU-MacOSX/main.o main.c
mkdir -p dist/Debug/GNU-MacOSX
gcc -o dist/Debug/GNU-MacOSX/tp build/Debug/GNU-MacOSX/main.o
BUILD SUCCESSFUL (total time: 271ms)
Cans someone tell me why it isn't reading the string I input?
btw, I'm portuguese :) .

Where did you allocate the space to store the password?
You do realize without the data-types you code is not possible to verify that it is correct.

Code:
aux->user = malloc(sizeof(user));
printf("Introduza a sua pass: ");
scanf("%s", aux->user->pass);
Where do you think this is pointing?
In main(), you initialise pass with things like this
user1->user->pass = "password";
But here, you also need to initialise pass with some memory you can read a string into.
