Tcl_GetOpenFile(3) Tcl Library Procedures Tcl_GetOpenFile(3)
__________________________________________________________________________________________________________________________________________________
NAME
Tcl_GetOpenFile - Get a standard IO File * handle from a channel. (Unix only)
SYNOPSIS
#include <tcl.h>
int
Tcl_GetOpenFile(interp, string, write, checkUsage, filePtr)
ARGUMENTS
Tcl_Interp *interp (in) Tcl interpreter from which file handle is to be obtained.
CONST char *string (in) String identifying channel, such as stdin or file4.
int write (in) Non-zero means the file will be used for writing, zero means it will be used for reading.
int checkUsage (in) If non-zero, then an error will be generated if the file wasn't opened for the access indicated by
write.
ClientData *filePtr (out) Points to word in which to store pointer to FILE structure for the file given by string.
_________________________________________________________________
DESCRIPTION
Tcl_GetOpenFile takes as argument a file identifier of the form returned by the open command and returns at *filePtr a pointer to the FILE
structure for the file. The write argument indicates whether the FILE pointer will be used for reading or writing. In some cases, such as
a channel that connects to a pipeline of subprocesses, different FILE pointers will be returned for reading and writing. Tcl_GetOpenFile
normally returns TCL_OK. If an error occurs in Tcl_GetOpenFile (e.g. string didn't make any sense or checkUsage was set and the file
wasn't opened for the access specified by write) then TCL_ERROR is returned and the interpreter's result will contain an error message. In
the current implementation checkUsage is ignored and consistency checks are always performed. |
Note that this interface is only supported on the Unix platform.
