NAME

6       bufsplit - split buffer into fields
7

SYNOPSIS

9       cc [ flag ... ] file ... -lgen [ library ... ]
10       #include <libgen.h>
11
12       size_t bufsplit(char *buf, size_t n, char **a);

DESCRIPTION

16       bufsplit()  examines the buffer, buf, and assigns values to the pointer
17       array, a, so that the pointers point to the first n fields in buf  that
18       are delimited by TABs or  NEWLINEs.
19
20
21       To  change the characters used to separate fields, call bufsplit() with
22       buf pointing to the string of characters, and n and a set to zero.  For
23       example,  to  use  colon (:), period (.), and  comma (,), as separators
24       along with TAB and NEWLINE:
25
26
27       bufsplit (":.,\t\n", 0, (char**)0 );
28

RETURN VALUES

30       The number of fields assigned in the array  a.  If  buf  is  zero,  the
31       return  value  is zero and the array is unchanged.  Otherwise the value
32       is  at least one.  The remainder of  the  elements  in  the  array  are
33       assigned the address of the null byte at the end of the buffer.
34

38         /*
39          * set a[0] = "This", a[1] = "is", a[2] = "a",
40          * a[3] = "test"
41          */
42         bufsplit("This\tis\ta\ttest\n", 4, a);

NOTES

46       bufsplit() changes the delimiters to null bytes in buf.

49       When  compiling multithreaded applications, the _REENTRANT flag must be
50       defined on the compile line.  This flag should only be used  in  multi‐
51       threaded applications.
