These are the API functions for the mmg2d library. These functions allow to load and save meshes and data defined on meshes; add, extract, or modify mesh data; and to call the library functions that perform meshing, remeshing, level-set discretization, and Lagrangian motion.

Meshes are here defined in terms of vertices and two-dimensional objects: triangles and quadrangles. Edges can also be represented. All of these entities can have a reference: an integer value that can serve as a group identifier. In addition mesh entities can have attributes such as "required" or "corner".

Data defined on meshes can be for example functions that are meant for level-set discretization, metric tensors that will govern edge lengths, and vector fields governing lagrangian motion. These data can be scalar, vector, or (symmetric) tensor-valued; and there can be more than one data item associated with a mesh entity. These data are often referred to as solutions.

Four of the functions here are referred to as "programs", because they perform the tasks for which Mmg is meant: (re)meshing, level-set discretization and Lagrangian motion. The other functions merely serve to load and save data and to perform pre- and post-processing. These programs actually behave much like independent programs: they send diagnostic output to stdout and in rare cases they may call the exit() function.
