Find the indices of the first and last non-blank characters in the given string. If the string contains no non-blank characters, the first index is returned set to 1 and last index is returned set to 0, i.e. "index1" is greater than "index2".

void chrFandl( const char $\ast$string, size_t $\ast$index1, size_t $\ast$index2 )

• For consistency with the Fortran routine CHR_FANDL, this function only checks for spaces. Other forms of whitespace characters such as tabs, line-feeds, etc are considered to be non-blank.
