enum shbuf_error

Error number specification. Enumeration values: SHBUF_NOERROR  No error occured. SHBUF_BUSY  The shared buffer is already opened by another client. SHBUF_NOTINNOTIFYMODE  The shbuf object is not in notify mode. SHBUF_SYSTEM_ERROR_BASE  Errors with a greater value than this use the libc errno.

Function Documentation

shbuf_error shbuf_get_errno (  void    )

Returns the current libshbuf specific error number. Returns: The current error number

void shbuf_perror (  const char *    p )

Emulates the libc perror() function but adds support for libshbuf specific errors. Parameters: p  String to be printed adjacent to the current error string Examples: shbuftest.c.

void shbuf_set_errno (  shbuf_error    e )

Sets the libshbuf specific error number. Mainly for internal purposes, but useful for signal handlers too. The libshbuf error number is thread specific. Parameters: e  Error number to be set

const char* shbuf_strerror (  shbuf_error    e, int    en )

Converts a pair of libshbuf and libc error numbers to a human readable string. The string is thread specific and freed on thread end. Following calls of this function may change the buffer returned. Parameters: e  libshbuf specific error number en  libc specific error number Returns: The error numbers in a textual representation

const char* shbuf_strerror2 (  void    )

Calls shbuf_strerror() with the current error numbers. Returns: The current error in a textual representation
