AIX5.2下调用 gunzip

SStallMan 2009-06-25 10:21:11
在aix下写的一个简单程序,需要用system 调用 gunzip命令来解压缩一个压缩文件,我如果把system调用放在main函数里面调用执行就没事,但是我现在是把加压缩的动作放在另外一个函数里面的,main函数的里面的函数会调用这个函数,如果压缩包小没事,如果压缩包大的话,解压过程中就会提示“警告调用”,然后程序就退出了,不知道这是怎么回事,大家有没有遇见过这种情况,感觉是内存什么出了问题了。

楼主把system函数设置的errno发出来看看
或者不用system用execl函数

难道是system创建子进程的内存不够?
Hello nmon user, This file introduces nmon for AIX 5L version 11e. This is a full version but seems to me to be stable enough for real work. But please test it a little before removing your older nmon version. If you are using the nmon2rrd or nmon Analyser, please also check these tool accept the new data files generated by nmon 11. Please feedback any problems to the developer Nigel Griffiths at nag@uk.ibm.com A zipped sample output file (not too big please) is also helpful. nmon has moved to the new IBM AIX Wiki Website which will mean that new versions can be release much more effectively and information updated on demand. See below for the URL. What is new in this latest nmon for AIX 5 version 11c ? Summary: 1) New Simpler Online Look 2) Volume Group Disk Stats 3) Paging Space Stats 4) Command Summary of TOP process data 5) Error messages go out to stderr 6) Network stats - fixed overflow problems. 7) Network errors and auto off 8) Protect against WLM library AIX memory leaks - if WLM off 9) AIX 5.2 Low ML - problem work around attempt 10) CPU Stats on POWER5 with AIX 5.3 and Shared Processor LPARs = SPLPAR. 11) Making nmon numbers match AIX commands 12) JFS numclient and maxclient numers 13) Wide windows in X Windows makes the columns wider in the Top view 14) WLM works again 15) nmon spots the VIO Server and reports the VIO Server version The full details of these 10 enhancements can be found at the new nmon Wiki Website http://www-941.haw.ibm.com/collaboration/wiki/display/WikiPtype/README+nmon+for+AIX+version+11e Please read the details before asking questions, particularly with number 10. Installing You will need to unzip the file: gunzip nmon4aix11e.tar.gz and then tar the files out: tar xvf nmon4linuxv11e.tar Please Note the New Places to Get nmon and nmon Information ----------------------------------------------------------- You can find all the latest nmon information and downloads at the new AIX Wiki - this includes the nmon for Linux too: Goto http://www.ibm.com/servers/eserver/pseries/community/ then select AIX Wiki then select Other Performance Tools then select nmon or go there directly via this URL http://www.ibm.com/collaboration/wiki/display/WikiPtype/nmon In addition nmon questions should now be raised at the Performance Tools Forum Goto http://www.ibm.com/servers/eserver/pseries/community/ and take the Performance Tools Forum Link There are loads of questions and answers there already.
