Convert an error code to a string
#include <sys/asoundlib.h>
const char *snd_strerror( int errnum );
- errnum
- An error number, which can be positive (i.e. the value of
errno)
or negative (i.e. a return code from a snd_* function).
libasound.so
The snd_strerror() function converts an error code to a string.
Its functionality is similar to that of
strerror()
(see the QNX Library Reference),
except that it returns the correct strings for sound error codes.
A pointer to the error message. Don't modify the string that it points to.
If snd_strerror() doesn't recognize the value for errnum,
it returns a pointer to the string “Unknown error.”
See the
wave.c example
in the appendix.
