NAME

       fnpathfind - find a file in a list of directories

SYNOPSIS

       #include <publib.h>

       int fnpathfind(const char *path, const char *tgt,
                            char *res, size_t max);

DESCRIPTION

       pathfind  looks  for  a  file  in  a  list of directories.  The argument `path' is a colon
       separated list of directories, typically the contents  of  an  environment  variable  like
       PATH,  MANPATH,  or  CDPATH.  The function will go through the directories in the path and
       look in each directory for a file given in argument `target' until it finds it.   Only  an
       exact match is reported, no wild cards or globbing.

       The names that are matched are formed by taking an element from the path and prepending it
       to target.  An empty element means the current directory, as does the name ".".

       The function returns -1 for failure (not found or error), or the total size for  the  full
       name (the full name may have been truncated when stored into result).

BUGS

       The  function  uses  dynamic  memory allocation and may therefore fail due to insufficient
       memory.

       It is not trivial to know in which directory the search ended.  This makes is difficult to
       continue the search.
