CURLOPT_AB...NIX_SOCKET(3) Library Functions Manual CURLOPT_AB...NIX_SOCKET(3) NAME CURLOPT_ABSTRACT_UNIX_SOCKET - abstract Unix domain socket SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ABSTRACT_UNIX_SOCKET, char *path); DESCRIPTION Enables the use of an abstract Unix domain socket instead of establish- ing a TCP connection to a host. The parameter should be a char * to a null-terminated string holding the path of the socket. The path is set to path prefixed by a NULL byte. This is the convention for abstract sockets, however it should be stressed that the path passed to this function should not contain a leading NULL byte. On non-supporting platforms, the abstract address is interpreted as an empty string and fails gracefully, generating a runtime error. This option shares the same semantics as CURLOPT_UNIX_SOCKET_PATH(3) in which documentation more details can be found. Internally, these two options share the same storage and therefore only one of them can be set per handle. DEFAULT NULL PROTOCOLS This functionality affects all supported protocols EXAMPLE int main(void) { CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_ABSTRACT_UNIX_SOCKET, "/tmp/foo.sock"); curl_easy_setopt(curl, CURLOPT_URL, "http://localhost/"); /* Perform the request */ curl_easy_perform(curl); } } AVAILABILITY Added in curl 7.53.0 RETURN VALUE curl_easy_setopt(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3). SEE ALSO CURLOPT_UNIX_SOCKET_PATH(3), unix(7) libcurl 2025-06-03 CURLOPT_AB...NIX_SOCKET(3)
