libcurl-symbols(3)

NAME
libcurl-symbols - libcurl symbol version information

libcurl symbols
This man page details version information for public symbols provided in the libcurl header files. This lists the first version in which the symbol was introduced and for some symbols two additional information pieces: The first version in which the symbol is marked "deprecated" - meaning that since that version no new code should be written to use the symbol as it is marked for getting removed in a future. The last version that featured the specific symbol. Using the symbol in source code will make it no longer compile error-free after that specified version. This man page is automatically generated from the symbols-in-versions file.
