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 (":.,	
", 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	is	a	test
", 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  mul-
       tithreaded applications.
