gFileReplaceContents: gFileReplaceContents

Description

Replaces the contents of file with contents of length bytes. If etag is specified (not NULL) any existing file must have that etag, or the error G_IO_ERROR_WRONG_ETAG will be returned.

Usage

gFileReplaceContents(object, contents, length, etag, make.backup, flags = "G_FILE_CREATE_NONE", cancellable = NULL, .errwarn = TRUE)

Arguments

object
input GFile.
contents
a string containing the new contents for file.
length
the length of contents in bytes.
etag
the old entity tag for the document, or NULL
make.backup
TRUE if a backup should be created.
flags
cancellable
optional GCancellable object, NULL to ignore.
.errwarn
Whether to issue a warning on error or fail silently

Value

A list containing the following elements:
retval
[logical] TRUE if successful. If an error has occurred, this function will return FALSE and set error appropriately if present.
new.etag
a location to a new entity tag for the document. This should be freed with gFree() when no longer needed, or NULL
error
a GError, or NULL

Details

If make.backup is TRUE, this function will attempt to make a backup of file. If cancellable is not NULL, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error G_IO_ERROR_CANCELLED will be returned. The returned new.etag can be used to verify that the file hasn't changed the next time it is saved over.
