reading and writing. The file is opened in binary mode on platforms where there is a difference. The file handle should be closed with close(). In case of errors, -1 is returned and error will be set.
fileOpenTmp
fn
int fileOpenTmp(string tmpl, out string nameUsed)Opens a file for writing in the preferred directory for temporary files (as returned by [glib.global.getTmpDir]).
tmpl should be a string in the GLib file name encoding containing a sequence of six 'X' characters, as the parameter to [glib.global.mkstemp]. However, unlike these functions, the template should only be a basename, no directory components are allowed. If template is null, a default template is used.
Note that in contrast to [glib.global.mkstemp] (and mkstemp()) tmpl is not modified, and might thus be a read-only literal string.
Upon success, and if name_used is non-null, the actual name used is returned in name_used. This string should be freed with [glib.global.gfree] when not needed any longer. The returned name is in the GLib file name encoding.
Parameters
tmpl | Template for file name, as in [glib.global.mkstemp], basename only, or null for a default template |
nameUsed | location to store actual name used, or null |
Returns
A file handle (as from open()) to the file opened for
Throws
[ErrorWrap]
