What does error conflicting types for '' mean?

Question

i got an error that said \"error: conflicting types for \'____\'. What does that mean?

Answer 1

it's probably because your function "_" already exists in your library. It happened to me with this function:

I was using stdio.h

int getline (char s[ ] , int lim) { int c, i;

for (i=0; i < lim-1 && (c=getchar())!=EOF && c!='\n'; ++i)
    s[i] = c;
if (c == '\n') {
    s[i] = c;
    ++i;
}
s[i] = '\0';
return i;

}

When I changed "getline" to "getlinexxx" and gcc compiled it:

int getlinexxx (char s[], int lim) { int c, i;

for (i=0; i < lim-1 && (c=getchar())!=EOF && c!='\n'; ++i)
    s[i] = c;
if (c == '\n') {
    s[i] = c;
    ++i;
}
s[i] = '\0';
return i;

}

And the problem was gone
