bufsplit(3GEN) String Pattern-Matching Library Functions bufsplit(3GEN)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 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);
NOTESbufsplit() 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 multi‐
threaded applications.
