getCRuntimeArgumentBlockLength

public static long getCRuntimeArgumentBlockLength()

Argv is an array of C strings (i.e. array of pointers to characters). Each entry points to a different C string corresponding to a program argument. The program argument strings themselves are located in a contiguous block of memory followed by the environment variables key-value strings:

 <argument_0>\n<argument_1>\n...<argument_n>\n
 <env_key_value_1>\n<env_key_value_2>\n...<env_key_value_n>\n
 

Returns:

maximum length of C chars that can be stored in the program argument part of the contiguous memory block without writing into the environment variables part.
