int getdelim(char **<var>bufptr</var>, size_t *<var>n</var>,
|

int <var>delim</var>, FILE *<var>fp</var>);

|
<p><strong>Description</strong><br>
|
||
|
|
<code>getdelim</code> reads a file <var>fp</var> up to and possibly including a specified
|
||
|
|
delimiter <var>delim</var>. The line is read into a buffer pointed to
|
||
|
|
by <var>bufptr</var> and designated with size *<var>n</var>. If the buffer is
|
||
|
|
not large enough, it will be dynamically grown by <code>getdelim</code>.
|
||
|
|
As the buffer is grown, the pointer to the size <var>n</var> will be
|
||
|
|
updated.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
<code>getdelim</code> returns <code>-1</code> if no characters were successfully read;
|
||
|
|
otherwise, it returns the number of bytes successfully read.
|
||
|
|
At end of file, the result is nonzero.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>getdelim</code> is a glibc extension.
|
||
|
|
</p>
|
||
|
|
<p>No supporting OS subroutines are directly required.
