waitfor()
Wait until a path exists
Synopsis:
#include <libgen.h>
int waitfor( const char *path,
int delay_ms,
int poll_ms );
Since:
BlackBerry 10.0.0
Arguments:
- path
- The path you want to wait for.
- delay_ms
- The maximum time, in milliseconds, that you want to wait for.
- poll_ms
- The number of millseconds to delay between checks.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The waitfor() function waits for the given path to exist, up to a maximum time of delay_ms milliseconds, checking every poll_ms milliseconds. If you're waiting for a mountpoint, polling isn't necessary; you can specify 0 for poll_ms in this case.
Returns:
- 0
- The path exists.
- -1
- An error occurred ( errno is set).
