ABAQUS UMAT/VUMAT IN C

Hi,

Can someone please tell me the procedure for writing ABAQUS UMAT/VUMAT in 'c' language. Everywhere I am finding examples in FORTRAN only. But the documentation says that it can be written in c/c++ also. Kindly tell me the procedure for writing in C and linking it to ABAQUS standard/explicit.

Thank you,

Ashok
