CURLOPT_PUT - make an HTTP PUT request

Added in curl 7.1

0, disabled

Deprecated since 7.12.1.

A parameter set to 1 tells the library to use HTTP PUT to transfer data. The data should be set with CURLOPT_READDATA(3) and CURLOPT_INFILESIZE(3). This option is deprecated since version 7.12.1. Use CURLOPT_UPLOAD(3).

static size_t read_cb(char *ptr, size_t size, size_t nmemb, void *userdata) { FILE *src = userdata; /* copy as much data as possible into the 'ptr' buffer, but no more than 'size' * 'nmemb' bytes */ size_t retcode = fread(ptr, size, nmemb, src); return retcode; } int main(void) { CURL *curl = curl_easy_init(); if(curl) { FILE *src = fopen("local-file", "r"); curl_off_t fsize = 123456; /* set this to the size of the input file */ /* we want to use our own read function */ curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_cb); /* enable PUT */ curl_easy_setopt(curl, CURLOPT_PUT, 1L); /* specify target */ curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/to/newfile"); /* now specify which pointer to pass to our callback */ curl_easy_setopt(curl, CURLOPT_READDATA, src); /* Set the size of the file to upload */ curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize); /* Now run off and do what you have been told */ curl_easy_perform(curl); } }
