NOTES
All names marked by a "#" are subroutine calls and have as their last
parameter ierror which returns the error code in case of an unsuccess‐
ful call. It is therefore recommended to check for the value of ierror
immediately after subroutine calls. All names marked by a "*" are
function calls and return some useful value other than ierror.
Simple rules for creating FORTRAN subroutine/function names from C
functions are listed below.
Mappings from substrings in C functions onto shorter substrings or sin‐
gle letters in FORTRAN wrappers:
C --> FORTRAN
TRY T
GET G
NODE ND
TYPE TP
All functions that return an integer or short integer are prefixed with
the letter "I". All functions that return a single precision or double
precision floating point value are prefixed with the letter "F". This
is to minimize the necessity of declaring functions. However functions
that return a short integer or a double precision floating point number
still have to be declared.
If after applying the above two rules, the FORTRAN name still exceeds
six characters in length, it is compressed to six by dropping the least
essential vowels.
