Node:File creation, Previous:Opening files at a low level, Up:Opening files at a low level
In older C code using low-level file routines, there was a function
called creat that was used for creating files. This function is
still included in GNU for compatibility with older C code, but is
considered obsolete. In order to create a file, instead of writing
creat (filename)
it is now considered better coding to practice to write the following code:
open (filename, O_WRONLY | O_CREAT | O_TRUNC)
