c - passing a pipe as an argument to sort -m -

i wondering if possible send multiple pipes lets 3 arguments merged sort -m in c.

for example execvp("sort", "sort", "-m", pipe1_read_end, pipe2_read_end, null)

if targeting linux, can pass strings of form:

/dev/fd/<number> 

...representing pipes, <number> is, of course, fd table entry number file descriptor in question. in fact, bash if run

sort -m <(something) <(something) 

for more os-agnostic solution, 1 typically uses named fifos (and bash <() construct if detects it's on operating system doesn't provide /dev/fd/).
