The PostgreSQL ESQL/C is an SQL application-programming interface (API) enables the C programmer to create custom applications with database-management capabilities. The PostgreSQL ESQL/C allows you to use a third-generation language with which you are familiar and still take advantage of the Structured Query Language (SQL).

ESQL/C consists of the following pieces of software:

• The ESQL/C libraries of C functions provide access to the database server.
• The ESQL/C header files provide definitions for the data structures, constants, and macros useful to the ESQL/C program.
• The ESQL/C preprocessor, is a source-code preprocessor that converts a C file containing SQL statements into an executable file.
