It's normally accepted (in POSIX systems) to allow a user to override
the temporary directory using the TMPDIR environment variable. The
following code will provide that behaviour, and, from your example
above, should just plug in where you need the system specific code.

Hope this helps,
Michael

#include <string.h>
#include <stdlib.h>
#include <stdio.h>

const char * getTempDir()
{
static char tempPath[_MAX_PATH];
static char * pTempPath = NULL;

if( NULL == pTempPath )
{
char * temp_env;
char * temp_dir;

temp_dir = temp_env = 0;

memset( tempPath, 0, sizeof( tempPath ) );

if( 0 == ( temp_env = getenv( "TMPDIR" ) ) )
{
strncpy( tempPath, "/tmp", sizeof( tempPath ) - 1 );
}
else
{
if( strlen( temp_env ) >= _MAX_PATH )
{
fprintf( stderr, "%s\n", "potential overflow "
"caused by TMPDIR environment variable" );
fflush( stderr );
exit( 1 );
}

strncpy( tempPath, temp_env, sizeof( tempPath ) - 1 );
}

pTempPath = tempPath;
}

return pTempPath;
}
