NAME

sam_readrminfo - Gets removable media file status

SYNOPSIS

cc [ flag … ] file … -L∕opt∕SUNWsamfs∕lib -R∕opt∕SUNWsamfs∕lib -lsam [ library … ]

#include "∕opt∕SUNWsamfs∕include∕rminfo.h"

int sam_readrminfo(const char * path , struct sam_rminfo * buf , size_t bufsize );

DESCRIPTION

sam_readrminfo() returns information about a removable media file. The removable media file is pointed to by path.

buf is a pointer to a sam_rminfo() structure into which information is placed concerning the file.

bufsize is the length of the user's buffer to which buf points. This should be equal to or greater than sizeof(struct sam_rminfo). The maximum number of overflow VSNs is 256. The following macro can be used to calculate the size of the sam_rminfo structure for n VSNs.

#define SAM_RMINFO_SIZE(n) (sizeof(struct sam_rminfo) + ((n) - 1) * sizeof(struct sam_section))

The contents of the structure pointed to by buf is documented in sam_request (3).

RETURN VALUES

Upon successful completion a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

sam_readrminfo() fails if one or more of the following are true:

EACCES: Search permission is denied for a component of the path prefix.
EFAULT: buf or path points to an illegal address.
EINTR: A signal was caught during the sam_readrminfo() function.
ELOOP: Too many symbolic links were encountered in translating path.
EMULTIHOP: Components of path require hopping to multiple remote machines and the file system does not allow it.
ENAMETOOLONG: The length of the path argument exceeds {PATH_MAX}, or the length of a path component exceeds {NAME_MAX} while {_POSIX_NO_TRUNC} is in effect.
ENOENT: The named file does not exist or is the null pathname.
ENOLINK: path points to a remote machine and the link to that machine is no longer active.
ENOTDIR: A component of the path prefix is not a directory.
EOVERFLOW: A component is too large to store in the structure pointed to by buf.
