resmgr_pathname()

QNX SDP8.0C Library ReferenceAPIDeveloper

Return the pathname associated with an ID

Synopsis:

#include <sys/iofunc.h>
#include <sys/resmgr.h>

int resmgr_pathname( int id,
                     unsigned flags, 
                     char* path, 
                     int maxbuf );

Arguments:

id: The link ID that resmgr_attach() returned.
flags: Use 0.
path: A pointer to a buffer where the function can store the path name.
maxbuf: The size of the buffer.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The resmgr_pathname() function returns the pathname associated with an id that's returned from resmgr_attach(), it's also the ctp->id value of all the resmgr callout functions.

If the id was obtained from calling resmgr_attach() with _RESMGR_FLAG_DIR specified, then the path name includes a trailing slash.

Returns:

The length of the path, including the terminating NUL character, or -1 if an error occurs (errno is set).

Errors:

EFAULT: A fault occurred in a server's address space when it tried to access the caller's message buffers.
ESRCH: The thread indicated by ctp->rcvid doesn't exist or its connection is detached.
ESRVRFAULT: A fault occurred when the kernel tried to access the buffers provided.

Classification:


Safety:
Cancellation point	No
Signal handler	Yes
Thread	Yes
