Question

我正在利用TBXML作为XML的馈赠和仪器探测记忆泄漏。

Instruments tells me there is a memory leak in function

- (TBXMLAttribute*) nextAvailableAttribute {
currentAttribute++;

if (!currentAttributeBuffer) {
currentAttributeBuffer = calloc(1, sizeof(TBXMLAttributeBuffer));
currentAttributeBuffer->attributes = (TBXMLAttribute*)calloc(MAX_ATTRIBUTES,sizeof(TBXMLAttribute));
currentAttribute = 0;
} else if (currentAttribute >= MAX_ATTRIBUTES) {
currentAttributeBuffer->next = calloc(1, sizeof(TBXMLAttributeBuffer));
currentAttributeBuffer->next->previous = currentAttributeBuffer;
currentAttributeBuffer = currentAttributeBuffer->next;
currentAttributeBuffer->attributes = (TBXMLAttribute*)calloc(MAX_ATTRIBUTES,sizeof(TBXMLAttribute));
currentAttribute = 0;
}

return &currentAttributeBuffer->attributes[currentAttribute];
}

页: 1

currentAttributeBuffer->attributes = (TBXMLAttribute*)calloc(MAX_ATTRIBUTES,sizeof(TBXMLAttribute));

是否有人解决了这一问题?

Answer 1

BEWARE.... instruments is informing You WHERE, the supplementeded memory was original Creat, NOT that the issue is in that line...... for example, if You do some with the identity sent and pollution it otherwise, instruments will show the line above, where it was establishing, NOT where You ....

Answer 2

calloc is a C function to allocate memory. You should call free currentAttributeBuffer; when you re finished with it. That will fix the memory leak.
