PR_SetErrorText 编辑

Sets the text associated with an error.

Syntax

#include <prerror.h>

void /wiki/en-US/docs/Mozilla/Projects/NSPR/Reference/PR_SetErrorText(/wiki/en-US/docs/Mozilla/Projects/NSPR/Reference/PRIntn textLength, const char *text)

Parameters

The function has these parameters:

textLength

The length of the text in the text. May be NULL. If not NULL, and if text is zero, the string is assumed to be a null-terminated C string. Otherwise the text is assumed to be the length specified and to possibly include NULL characters (as might occur in a multilingual string).

text

The text to associate with the error.

Description

The text is copied into the thread structure and remains there until the next call to /wiki/en-US/docs/Mozilla/Projects/NSPR/Reference/PR_SetError. If there is error text already present in the thread, the previous value is first deleted. The new value is copied into storage allocated and owned by NSPR and remains there until the next call to /wiki/en-US/docs/Mozilla/Projects/NSPR/Reference/PR_SetError or another call to /wiki/en-US/docs/Mozilla/Projects/NSPR/Reference/PR_SetErrorText.

NSPR makes no use of this function. Clients may use it for their own purposes.
