Its API is similar to support_capture_subprocess, but rather creates a new process based on the input path and arguments. Under the hoods it uses posix_spawn to create the new process. It also allows the use of other support_capture_* functions to check for expected results and free the resources. Checked on x86_64-linux-gnu. * support/Makefile (libsupport-routines): Add support_subprocess, xposix_spawn, xposix_spawn_file_actions_addclose, and xposix_spawn_file_actions_adddup2. (tst-support_capture_subprocess-ARGS): New rule. * support/capture_subprocess.h (support_capture_subprogram): New prototype. * support/support_capture_subprocess.c (support_capture_subprocess): Refactor to use support_subprocess and support_capture_poll. (support_capture_subprogram): New function. * support/tst-support_capture_subprocess.c (write_mode_to_str, str_to_write_mode, test_common, parse_int, handle_restart, do_subprocess, do_subprogram, do_multiple_tests): New functions. (do_test): Add support_capture_subprogram tests. * support/subprocess.h: New file. * support/support_subprocess.c: Likewise. * support/xposix_spawn.c: Likewise. * support/xposix_spawn_file_actions_addclose.c: Likewise. * support/xposix_spawn_file_actions_adddup2.c: Likewise. * support/xspawn.h: Likewise.
