c - How do I access a function variable from main() -

-

i'm attempting use character compare function in main() while ignoring case sensitivity. there way call toupper(ch1) , toupper(ch2) main if -i (for case insensitivity) raised can reuse code. 

int charactercompare( file *file1, file *file2, char file1name[], char file2name[] ) {    int ch1, ch2;    int differ = 0;        {      ch1 = fgetc( file1 );       ch2 = fgetc( file2 );       differ++;        if ( feof( file1 ) && !feof( file2 ) )       {            printf( "eof on %s\n", file1name );          return 1;                }       else if ( feof( file2 ) && !feof( file1) )       {          printf( "eof on %s\n", file2name );          return 1;       }        if (ch1 != ch2)       {          printf( "files differ: char %d\n", differ );          return 1;       }         }     while( ( !feof( file1 ) ) && ( !feof( file2 ) ) && (ch1 == ch2) );     printf( "files equal\n" );     return 0; }

long answer (not tested, shoukld idea):

int compare(char ch1, char ch2, int ignorecase) {   if (ignorecase)   {     ch1 = toupper(ch1) ;     ch2 = toupper(ch2) ;   }    return ch1 == ch2 ; }   int charactercompare( file *file1, file *file2, char file1name[], char file2name[],                       int ignorecase ) {    int ch1, ch2;    int differ = 0;        {     ch1 = fgetc( file1 );       ch2 = fgetc( file2 );       differ++;        if ( feof( file1 ) && !feof( file2 ) )       {            printf( "eof on %s\n", file1name );          return 1;                }       else if ( feof( file2 ) && !feof( file1) )       {          printf( "eof on %s\n", file2name );          return 1;       }        if (compare(ch1, ch2, ignorecase))       {          printf( "files differ: char %d\n", differ );          return 1;       }         }     while( ( !feof( file1 ) ) && ( !feof( file2 ) ) && (ch1 == ch2) );     printf( "files equal\n" );     return 0; }

and in main e.g :

ignorecase = argv[1] == "-i" ; int different = charactercompare(f2, f2, name1, name2, ignorecase) ;
