bufsplit(3G)bufsplit(3G)NAMEbufsplit - split buffer into fields
SYNOPSIS
cc [flag ...] file ... -lgen [library ...]
#include <libgen.h>
size_t bufsplit (char *buf, size_t n, char **a);
DESCRIPTIONbufsplit 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 VALUE
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);
NOTESbufsplit changes the delimiters to null bytes in buf.
