From eb15151705d47d23da844449126cc6b4879f110e Mon Sep 17 00:00:00 2001 From: wm4 Date: Tue, 17 Dec 2013 02:02:25 +0100 Subject: Move options/config related files from mpvcore/ to options/ Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok. --- options/path.c | 238 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 238 insertions(+) create mode 100644 options/path.c (limited to 'options/path.c') diff --git a/options/path.c b/options/path.c new file mode 100644 index 0000000000..a2b2f135c5 --- /dev/null +++ b/options/path.c @@ -0,0 +1,238 @@ +/* + * Get path to config dir/file. + * + * Return Values: + * Returns the pointer to the ALLOCATED buffer containing the + * zero terminated path string.
