Function
Vipsguess_libdir
Declaration [src]
const char*
vips_guess_libdir (
const char* argv0,
const char* env_name
)
Description [src]
vips_guess_libdir() tries to guess the install directory (usually the
configure libdir, or $prefix/lib). You should pass
in the value of argv[0] (the name your program was run as) as a clue to
help it out, plus the name of the environment variable you let the user
override your package install area with (eg. “VIPSHOME”).
On success, vips_guess_libdir() returns the libdir it discovered, and as a
side effect, sets the prefix environment variable (if it’s not set).
Don’t free the return string!
