Declaration
int mkstemp(char* template);
Requirements
* The parameter template must be a modifiable, null-terminated character array. * The contents of template must be in the format of a valid file path, with six trailing 'X's. * The parameter template must not have been used in a previous invocation of mkstemp.
emantics
* The trailing 'X's in template are overwritten to generate an unique file name for the resulting temporary file. * The function reports a valid file descriptor to a temporary file on success; on failure, it reports -1.
