Subprocesses in C for RAD
The following are subprocesses in the C language for RAD:
-
exec_params_t *rad_exec_params_alloc
-
Allocates a control structure for executing a subprocess.
-
void rad_exec_params_free(exec_params_t *params);
-
Frees a subprocess control structure, params.
-
void rad_exec_params_set_cwd(exec_params_t *params, const char *cwd);
-
Sets the current working directory,
cwd
, in a subprocess control structure,params
. -
void rad_exec_params_set_env(exec_params_t *params, const char **envp);
-
Sets the environment,
envp
, in a subprocess control structure,params
. -
void rad_exec_params_set_loglevel(exec_params_t *params, rad_logtype_t loglevel);
-
Sets the RAD log level,
loglevel
, in a subprocess control structure,params
. -
int rad_exec_params_set_stdin(exec_params_t *params, int fd);
-
Sets the stdin file descriptor,
fd
, in a subprocess control structure,params
. -
int rad_exec_params_set_stdout(exec_params_t *params,int fd);
-
Sets the stdout file descriptor,
fd
, in a subprocess control structure,params
. -
int rad_exec_params_set_stderr(exec_params_t *params, int fd);
-
Sets the stderr file descriptor,
fd
, in a subprocess control structure,params
. -
int rad_forkexec(exec_params_t *params, const char **argv, exec_result_t *result);
-
Uses the supplied subprocess control structure,
params
, to fork and execute (execv) the supplied args,argv
. If result is notNULL
, it is updated with the subprocess pid and file descriptor details. -
int rad_forkexec_wait(exec_params_t *params, const char **argv, int *status);
-
Uses the supplied subprocess control structure,
params
, to fork and execute (execv) the supplied args,argv
. If status is notNULL
, it is updated with the exit status of the subprocess. This function will wait for the subprocess to terminate before returning. -
int rad_wait(exec_params_t *params, exec_result_t *result, int *status);
-
Uses the supplied subprocess control structure, params, to wait for a previous invocation of rad_forkexe to complete. If result is not
NULL
, it is updated with the subprocesspid
and file descriptor details. If status is notNULL
, it is updated with the exit status of the subprocess. This function will wait for the subprocess to terminate before returning.
