bufsplit(3G)
bufsplit --
split buffer into fields
Synopsis
cc [flag . . . ] file . . . -lgen [library] . . .
#include <libgen.h>
size_t bufsplit(char *buf, size_t n, char **a);
Description
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 new-line:
bufsplit(":.,\t\n", 0, (char**)0);
Return values
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.
Examples
/*
* set a[0] = "This", a[1] = "is", a[2] = "a",
* a[3] = "test"
*/
bufsplit("This\tis\ta\ttest\n", 4, a);
Notices
bufsplit changes the delimiters to null bytes in
buf.
