bufsplit - split buffer into fields
cc [flag ...] file ... -lgen [library ...]
size_t bufsplit (char *buf, size_t n, char **a);
bufsplit examines the buffer, buf, and assigns values to the pointer
array, a, so that the pointers point to the first n fields in buf that
are delimited by tabs or new-lines.
To change the characters used to separate fields, call bufsplit with buf
pointing to the string of characters, and n and a set to zero. For
example, to use ':', '.', and ',' as separators along with tab and newline:
bufsplit (":.,\t\n", 0, (char**)0 );
The number of fields assigned in the array a. If buf is zero, the return
value is zero and the array is unchanged. Otherwise the value is at
least one. The remainder of the elements in the array are assigned the
address of the null byte at the end of the buffer.
* set a = "This", a = "is", a = "a",
* a = "test"
bufsplit("This\tis\ta\ttest\n", 4, a);
bufsplit changes the delimiters to null bytes in buf.
