How to substring ?

[appsforum]

Hi All,

Does anyone know, how to substring a set of characters
given the start and end positions ?

I am trying to cut a long string into chunks of 250
characters and store them in an array.

Thanks in advance.

char buff[100][251];
for ( i = 0, j = 0 ; i < n ; i += 250, j++ ) {
  strncpy( buff[j], &line[i], 250 );
  buff[j][250] = '\0';
}
