Further information
1. This routine returns an absolute path to the file name it gets as input and optionally checks whether access is allowed according to the current restrictions.
2. The function will return an error code if option
XPRM_RCHK_IODRV is used and the provided path includes an IO driver different from
":" (default driver) and
"tmp:" (temporary directory). With this option, the prefix "tmp:" is replaced by the absolute path to the temporary directory and
":" is removed before path expansion. Note that in this mode the leading blanks of the input string are trimmed before any processing.
