Is there a good method for making a FILE * that simply focuses to an area in memory rather than on a disk?

#include <cstdio>

int main()
{
    FILE *pipe = popen("curl --header \"x-api-key:ABCD\" -s https://api.test.se/api/mydata", "r");

    while( // read data from pipe is true )
    {
         // process data
    }
    fclose(pipe);
}

FILE* pipe = _popen("curl --header \"x-api-key:ABCD\" -s https://api.test.se/api/mydata", "r");

	while (true)
	{
		pipe->_Placeholder;
		break;
	}

	fclose(pipe);

#include <stdio>
 #include <cstdlib>

FILE *pipe = popen( ... );

char *buff = NULL;
size_t blen = 0;
while( getline(&buff, &blen, pipe) > 0) {
    // process input data in buff;
}
free(buff);

std::ifstream ifs("curl --header \"x-api-key:ABCD\" -s https://api.test.se/api/mydata");
	while (ifs.good())
	{
		std::string line;
		while (std::getline(ifs, line))
		{
			std::cout << line.c_str() << std::endl;
		}
	}

char buffer[132];
FILE* pipette = _popen("curl --header \"x-api-key:ABCD\" -s https://api.test.se/api/mydata", "r");
while (fgets(buffer, 132, pipette))
{
    printf("%s", buffer);
}
