int io_mknod ( resmgr_context_t *ctp, io_mknod_t *msg, RESMGR_HANDLE_T *handle, void *reserved )
Classification: Connect
Default handler: none
Helper functions: iofunc_mknod()
Client functions: mknod(), mkdir(), mkfifo()
Messages: _IO_CONNECT, subtype _IO_CONNECT_MKNOD
Data structure:
struct _io_connect { // internal fields (as described above) uint16_t path_len; uint8_t extra_type; uint16_t extra_len; char path [1]; }; struct _io_connect_link_reply { uint32_t reserved1; uint32_t file_type; uint8_t eflag; uint8_t reserved2[1]; uint16_t chroot_len; uint32_t umask; uint16_t nentries; uint16_t path_len; }; struct _io_connect_ftype_reply { uint16_t status; /* Typically an errno */ uint16_t reserved; uint32_t file_type; /* _FTYPE_? in sys/ftype.h */ }; typedef union { struct _io_connect connect; struct _io_connect_link_reply link_reply; struct _io_connect_ftype_reply ftype_reply; } io_mknod_t;
Description: Creates a new filesystem entry point. The message is issued to create a file, named by the path member, using the filetype encoded in the mode member (from the "internal fields" part of the struct _io_connect structure, not shown).
This is really used only for the mkfifo(), mkdir(), and mknod() client functions.
Returns: The status via the helper macro _RESMGR_STATUS().
