NAME

6       libcurl-symbols - libcurl symbol version information

libcurl symbols

9       This  man  page details version information for public symbols provided
10       in the libcurl header files. This lists the first version in which  the
11       symbol  was  introduced and for some symbols two additional information
12       pieces:
13
14       The first version in which the symbol is marked "deprecated" -  meaning
15       that since that version no new code should be written to use the symbol
16       as it is marked for getting removed in a future.
17
18       The last version that featured the specific symbol. Using the symbol in
19       source code will make it no longer compile error-free after that speci‐
20       fied version.
21
22       This man page is automatically generated from  the  symbols-in-versions
23       file.
