Thanks to everyone's comments I solved the problem. I am posting the code here, so others might find it beneficial.

void getFileHash(char *fileName){

unsigned char result[2*SHA_DIGEST_LENGTH];
unsigned char hash[SHA_DIGEST_LENGTH];
int i;
FILE *f = fopen(fileName,"rb");
SHA_CTX mdContent;
int bytes;
unsigned char data[1024];

if(f == NULL){
    printf("%s couldn't open file\n",fileName);
    exit(1);
}

SHA1_Init(&mdContent);
while((bytes = fread(data, 1, 1024, f)) != 0){

    SHA1_Update(&mdContent, data, bytes);
}

SHA1_Final(hash,&mdContent);
