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 [2]; uint8_t eflag; uint8_t reserved2 [3]; uint32_t umask; uint16_t nentries; uint16_t path_len; }; typedef union { struct _io_connect connect; struct _io_connect_link_reply link_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.
