Syntax :
int fread(void *Buffer,int Size,int Count,FILE *ptr); u need to pass the address of the structure, not the direct pointer. u need to declare structure variable. node: void *Buffer receives address of the variable, not the pointer. That's why ur getting incorrect output.

Hi pietroamaral,
Actually I am more comfortable with fprintf than fwrite, please have a look on the below code. It worked for me.#include <stdio.h> #include <stdlib.h> #include <string.h> struct dados { char matr[50]; char ele[50]; float ela[50]; float final[50]; int freq[50]; float recu[50]; }; int main() { struct dados *object = NULL; object = (struct dados *)malloc(sizeof(struct dados)); strcpy(object->matr,"diario"); FILE *fp = NULL; fp = fopen("dataTest.txt","w"); if (fp != NULL) { fprintf(fp,"%s",object->matr); } close(fp); return 0; } -
