int io_fdinfo ( resmgr_context_t *ctp, io_fdinfo_t *msg, RESMGR_OCB_T *ocb )
Classification: I/O
Default handler: iofunc_fdinfo_default()
Helper functions: iofunc_fdinfo()
Client function: iofdinfo()
Messages: _IO_FDINFO
Data structure:
struct _io_fdinfo { uint16_t type; uint16_t combine_len; uint32_t flags; uint32_t path_len; uint32_t reserved; }; struct _io_fdinfo_reply { uint32_t zero [2]; struct _fdinfo info; }; typedef union { struct _io_fdinfo i; struct _io_fdinfo_reply o; } io_fdinfo_t;
Description: This function is used to allow clients to retrieve information directly about the attributes and pathname which is associated with a file descriptor. The client-side function iofdinfo() is used. The path string implicitly follows the struct _io_fdinfo_reply data structure. Use of the default function is sufficient for discretely-manifested pathname resource managers.
Returns: The length of the path string being returned is set via the helper macro _IO_SET_FDINFO_LEN().
