</div>
<p>The <strong>QlgStatvfs()</strong> function, like the <strong>
statvfs()</strong> function, gets status information about the file system that
contains the file named by the <em>path</em> argument. The difference is that
the <strong>QlgStatvfs()</strong> function takes a pointer to a Qlg_Path_Name_T
structure, while <strong>statvfs()</strong> takes a pointer to a character
string.</p>
<p>Limited information on the <em>path</em> parameter is provided here. For
more information on the <em>path</em> parameter and for a discussion of other
parameters, authorities required, return values, and related information, see
<a href="statvfs.htm">statvfs()</a>--Get File System Information.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong><em>path</em></strong></dt>
<dd>(Input) A pointer to a Qlg_Path_Name_T structure that contains a path name
or a pointer to a path name of the file from which file system information is
required. For more information on the Qlg_Path_Name_T structure, see <a href=
"../apiref/pns.htm">Path name format</a>.</dd>

<h3>Example</h3>
<p>See <a href="../apiref/aboutapis.htm#codedisclaimer">Code disclaimer information</a>
for information pertaining to code examples.</p>
<p>The following example gets status information about a file system:</p>
<pre>
#include <sys/statvfs.h>
#include <stdio.h>
#include <sys/types.h>
main() {
struct statvfs info;
#define mypath "/"
const char US_const[3]= "US";

typedef struct pnstruct
{

/* length of the path name or must */
/* be a pointer to the path name. */
};
struct pnstruct path;
/***************************************************************/
/* Initialize Qlg_Path_Name_T parameters */
/***************************************************************/
memset((void*)path name, 0x00, sizeof(struct pnstruct));
path.qlg_struct.CCSID = 37;
memcpy(path.qlg_struct.Country_ID,US_const,2);
memcpy(path.qlg_struct.Language_ID,Language_const,3);
path.qlg_struct.Path_Type = QLG_CHAR_SINGLE;
path.qlg_struct.Path_Length = sizeof(mypath)-1;
path.qlg_struct.Path_Name_Delimiter[0] = '/';
memcpy(path.pn,mypath,sizeof(mypath)-1);
if (-1 == QlgStatvfs((Qlg_Path_Name_T *)path name, &info))
perror("QlgStatvfs() error");
else {
puts("QlgStatvfs() returned the following information");
puts("about the Root ('/') file system:");
printf(" f_bsize : %u\n", info.f_bsize);
printf(" f_blocks : %08X%08X\n",
*((int *)&info.f_blocks[0]),
*((int *)&info.f_blocks[4]));
printf(" f_bfree : %08X%08X\n",
*((int *)&info.f_bfree[0]),
*((int *)&info.f_bfree[4]));
printf(" f_files : %u\n", info.f_files);
printf(" f_ffree : %u\n", info.f_ffree);
printf(" f_fsid : %u\n", info.f_fsid);
printf(" f_flag : %X\n", info.f_flag);
printf(" f_namemax : %u\n", info.f_namemax);
printf(" f_pathmax : %u\n", info.f_pathmax);
printf(" f_basetype : %s\n", info.f_basetype);
}
}
</pre>
<p>Output: The following information will vary from file system to file
system.</p>
<pre>
QlgStatvfs() returned the following information
about the Root ('/') file system:
f_bsize : 4096
f_blocks : 00000000002BF800
f_bfree : 0000000000091703
f_files : 4294967295
f_ffree : 4294967295
f_fsid : 0
f_flag : 1A
f_namemax : 255
f_pathmax : 4294967295
f_basetype : "root" (/)
