NAME¶

rtapi_string.h - RTAPI wrappers for linux kernel functionality

SYNTAX¶

#include <rtapi_string.h>

char **rtapi_argv_split(rtapi_gfp_t g, const char *argstr, int *argc);

void rtapi_argv_free(char **argv);

char *rtapi_kstrdup(const char *s, rtapi_gfp_t t);

DESCRIPTION¶

In kernel space, each rtapi_xxx or RTAPI_XXX identifier is mapped to the underlying kernel functionality, if available.

In userspace, or in kernels where the underlying functionality is not provided by a kernel, generally another implementation--possibly with reduced functionality--is provided. (For example, the userspace implementation for rtapi_device_register always succeeds)

REALTIME CONSIDERATIONS¶

Call only from within init/cleanup code, not from realtime tasks. This function is not available from non-realtime code.

RETURN VALUE¶

As in Linux.
