     21 
     22 ~~~c
     23 #include <curl/curl.h>

     28 # DESCRIPTION
     29 
     30 Pass a long. Sets the number of probes to send before dropping
     31 the connection. Not all operating systems support this option.
     32 (Added in 8.9.0)
     33 
     34 The maximum value this option accepts is INT_MAX or whatever your
     35 system allows.
     36 Any larger value is capped to this amount.
