For example, to use colon (\|:\|), period (\|.\|), and comma (\|,\|), as separators along with \fBTAB\fR and \fBNEWLINE:\fR .sp .LP \fBbufsplit (":.,\et\en", 0, (char**)0 );\fR .SH RETURN VALUES .sp .LP The number of fields assigned in the array \fIa\fR. If \fIbuf\fR 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. .SH EXAMPLES .LP \fBExample 1 \fRExample of \fBbufsplit()\fR function. .sp .in +2 .nf /* * set a[0] = "This", a[1] = "is", a[2] = "a", * a[3] = "test" */ bufsplit("This\etis\eta\ettest\en", 4, a); .fi .in -2 .SH NOTES .sp .LP \fBbufsplit()\fR changes the delimiters to null bytes in \fIbuf\fR. .sp .LP When compiling multithreaded applications, the \fB_REENTRANT\fR flag must be defined on the compile line. This flag should only be used in multithreaded applications. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
