mathlink.h

• MathLink C functions are declared in the file mathlink.h, which should be included in the source code for any MathLink-compatible program.

• Unless you specify #define MLPROTOTYPES 0 before #include "mathlink.h", the MathLink functions will be included with standard C prototypes.

• The following special types are defined in mathlink.h:

• The following constants are set up when a MathLink template file is processed:

• All functions defined in mathlink.h are C language functions. They can be called from other languages with appropriate wrappers.

• All functions defined in mathlink.h which return int yield a nonzero value if they succeed; otherwise they return 0 and have no effect.

• In a program set up using MathLink templates (.tm files), the link to Mathematica is called stdlink.

• All functions defined in mathlink.h which put data to a link do not deallocate memory used to store the data. Functions which get data from a link may allocate memory to store the data. Functions which get data from a link will not return until the necessary data becomes available. A yield function can be registered to be called during the wait.
