.SH SYNOPSIS
|
|
.B #include <vips/vips.h>
|
|
|
|
.B const char *im_guess_prefix( const char *argv0,
|
|
.B const char *env_name )
|

|
.SH DESCRIPTION
|
|
.B im_guess_prefix(3)
|
|
tries to guess the install directory. 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,
|
|
.B im_guess_prefix(3)
|
|
returns the prefix it discovered, and as a side effect, sets the environment
|
|
variable (if it's not set).
|
|
|
|
.B im_guess_prefix(3)
|
|
is useful for programs in the VIPS distribution and contrib which need to be
|
|
able to find data files.
|
|
|
|
Don't free the return string!
|
|
|
|
.B im_guess_libdir(3)
|
|
works exactly as
|
|
.B im_guess_prefix(3)
|
|
but, if vips has not been moved since configure, returns the libdir configure
|
|
setting. If vips has been moved, it returns prefix/lib.
|
|
|
|
.SH RETURN VALUE
|
|
The function returns NULL on failure.
