Add getservbyname and getservbyport (#204) For every call of getservbyname/getservbyport the lookup of /etc/services is done by opening the file and parsing each line one-by-one. This is slow, but the implementation is simple. This change also adds fixes for the gethostbyname function. 2021-07-04 23:31:42 +00:00			`#ifndef COSMOPOLITAN_LIBC_DNS_SERVICESTXT_H_`

Add protoent and netent (#209) The implementations of the getproto* functions follow from the getserv* functions: same static name allocation, same type of internal function that opens a file to search, aliases are not written to the struct, same type of error handling/returns. This changes also fixes a getaddrinfo AI_PASSIVE memory error. When getaddrinfo is passed name = NULL and AI_PASSIVE in hints->ai_flags, it was setting the s_addr value to INADDR_ANY but not returning the addrinfo pointer via *res = ai. This caused a free(NULL) memory error when the caller tried to free res, because the caller expects res to be a valid pointer to a struct addrinfo. Our non-standard API parseport() has been updated to use strtoimax. strtoimax has an extra parameter endptr to store where the parsing was terminated. endptr is used in parseport to check if the provided string was valid. 2021-07-10 19:36:35 +00:00			`int LookupServicesByPort(const int, char , size_t, char , size_t,`

Make whitespace changes Status lines for Emacs and Vim have been added to Python sources so they'll be easier to edit using Python's preferred coding style. Some DNS helper functions have been broken up into multiple files. It's nice to have one function per file whenever possible, since that way we don't need -ffunction-sections. Another reason it's good to have small source files, is because the build will be enforcing resource limits on compilation and testing soon. 2021-08-13 10:20:45 +00:00			`char GetNtServicesTxtPath(char , uint32_t);`
