BUFSPLIT(3GEN) String Pattern-Matching Library Functions BUFSPLIT(3GEN)

NAME

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 NEWLINEs.

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 colon (:), period (.), and comma (,), as
separators along with TAB and NEWLINE:

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

Example 1: Example of bufsplit() function.

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

NOTES

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

When compiling multithreaded applications, the _REENTRANT flag must
be defined on the compile line. This flag should only be used in
multithreaded applications.
