Get C/C++ Compiler Flags for hdf5lib

Description

Provides the required C/C++ compiler flags to find the HDF5 header files bundled with the hdf5lib package.

Usage

c_flags(api = "latest")

Arguments

api

A numeric value specifying the HDF5 API version to use (e.g., 1.14 or 114 for v1.14), or the string "latest". This adds a preprocessor directive like -DH5_USE_114_API_DEFAULT to ensure that the compiled code uses symbols compatible with a specific version of the HDF5 API. This is useful for maintaining compatibility with older HDF5 versions. Supported values are 2.0, 1.14, 1.12, 1.10, 1.8, and 1.6. Defaults to "latest", which corresponds to the newest supported API version.

Value

A scalar character vector containing the compiler flags (e.g., the -I path to the package's inst/include directory).
