snd_strerror()

Convert an error code to a string

Synopsis:

#include <sys/asoundlib.h>

const char *snd_strerror( int errnum );

Arguments:

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).

Library:

libasound.so

Description:

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.

Returns:

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."

Examples:

See the wave.c example in the appendix.

Classification:

QNX Neutrino

Safety:
Cancellation point	No
Interrupt handler	No
Signal handler	Yes
Thread	Yes
