+/****f* silcutil/SilcBufferAPI/silc_buffer_strchr
+ *
+ * SYNOPSIS
+ *
+ *    static inline
+ *    unsigned char *silc_buffer_strchr(SilcBuffer sb, int c, SilcBool first);
+ *
+ * DESCRIPTION
+ *
+ *    Returns pointer to the occurence of the character `c' in the buffer
+ *    `sb'.  If the `first' is TRUE this finds the first occurene of `c',
+ *    if it is FALSE this finds the last occurence of `c'.  If the character
+ *    is found the `sb' data area is moved to that location and its pointer
+ *    is returned.  The silc_buffer_data call will return the same pointer.
+ *    Returns NULL if such character could not be located and the buffer
+ *    remains unmodified.
+ *
+ *    This call is equivalent to strchr(), strrchr(), memchr() and memrchr()
+ *    except it works with SilcBuffer.
+ *
+ * NOTES
+ *
+ *    This searches only the data area of the buffer.  Head and tail area
+ *    are not searched.
+ *
+ *    The `sb' data need not be NULL terminated.
+ *
+ ***/
