.TH SDL_GetRevision 3 "SDL 3.1.0" "SDL" "SDL3 FUNCTIONS"
.SH NAME
SDL_GetRevision \- Get the code revision of SDL that is linked against your program\[char46]
.SH SYNOPSIS
.nf
.B #include \(dqSDL3/SDL.h\(dq
.PP
.BI "const char* SDL_GetRevision(void);
.fi
.SH DESCRIPTION
This value is the revision of the code you are linked with and may be
different from the code you are compiling with, which is found in the
constant 
.BR SDL_REVISION
\[char46]

The revision is arbitrary string (a hash value) uniquely identifying the
exact revision of the SDL library in use, and is only useful in comparing
against other revisions\[char46] It is NOT an incrementing number\[char46]

If SDL wasn't built from a git repository with the appropriate tools, this
will return an empty string\[char46]

Prior to SDL 2\[char46]0\[char46]16, before development moved to GitHub, this returned a
hash for a Mercurial repository\[char46]

You shouldn't use this function for anything but logging it for debugging
purposes\[char46] The string is not intended to be reliable in any way\[char46]

.SH RETURN VALUE
Returns an arbitrary string, uniquely identifying the exact revision of the
SDL library in use\[char46]

.SH AVAILABILITY
This function is available since SDL 3\[char46]0\[char46]0\[char46]
