Schily's LIBRARY FUNCTIONS                            FINDLINE(3)


     findline() - finds a line that has a matching field


     int findline(fname,delim,string,field,array,arraysize)
          char *fname;   /* file name */
          char delim;    /* field delimiter */
          char *string;  /* string to match */
          int field;     /* field number to match, 0-n */
          char *array[]; /* array to fill pointers in */
          int arraysize; /* number of entries in the arrays */


     findline() retrieves specific fields from the first line  of
     the file fname.

     findline() fills in array with pointers to strings that make
     up  the  fields  on  the line. The strings are allocated new
     storage.  The field delimiter, delim, is used  to  break  up
     each  line  of the file into fields. string is the string to
     match. fieldno is the field number to match. Fields are num-
     bered 0..n. array is an array of pointers to fill in. array-
     size is the number of elements in the array.


     +1   match.

     -1   no match.

     -2   arg error.

     -3   cannot open file.

     -4   not enough memory to allocate space for fields.


     Each line of the file must be less than 512 characters long.
