The Complete SPRLIB & ANNLIB
init_full_fname
- initializes the filename expansion mechanism
SYNOPSIS
ARGUMENTS
None.
RETURNS
Nothing.
FUNCTION
SPRANNLIB has a function find_full_fname which can expand a filename by
placing alternative search paths in front of them. To build the list of
alternative search paths (*AltPaths[], see FILE-IO-variables) the
environment variable SPR_DATA is read using the C-function getenv. If the
variable is not found, a warning will be given. Entries in this path environment
variable should be separated by one of the characters ':', ';', ','
or ' '. Under MS-DOS, the ';' is not a valid field separator.
The first entry in *AltPaths[] will always be '.', or the current
directory. The maximum number of entries is given by MAXALTPATHS (see
LIBRARY-flags).
NOTE
This function is called by sprinit.
