The iscobolc library provides the following functions:

For each one of the above functions, an additional extended function is provided to work in multi-thread environments.

These functions are defined in the iscobolc.h header file, that is installed with isCOBOL in the folder $ISCOBOL_HOME/native/include.

Note: COBOL programs called thru isCobolCall and isCobolFunc are not aware of the C environment. An environment variable set by the C program cannot be retrieved by the COBOL program using the ACCEPT FROM ENVIRONMENT statement. In order to set an environment variable for the COBOL program, create a separate COBOL program that sets the variable using the SET ENVIRONMENT statement and then call this program using isCobolFunc.
