E-Z (Easy) Channel Access

EZCA was originaly designed to provide a simplified interface to Channel Access, intended for C programs which do not need all the capabilities of the full API. In practice though if you have problems getting code to work that uses EZCA or if you get unexplained failures or crashes, you will get less help from the EPICS community in debugging the issue than you will if you use the native CA API. The CA API is not hard to use, and EZCA is not maintained as aggressively as the underlying CA library. Additional language interfaces using EZCA are also available, see below.
