So here is the bit of my code that\'s giving me problems: void childProcessHandler(string command){ int argCounter = 0;
when i run my code below and type in \"ls\" at the prompt it runs ls in the terminal but then just sits there and doesnt print my prompt again.How do I get control to go back to the parent process?
I\'m currently wrapping a command line tool (espeak) with Tcl/Tk, and I have figured this out so far:
currently working on program which recieves input command for linux shell and executing them creating child process.
I get \"passing argument 2 of ‘execvp’ from incompatible pointer type\" and expected ‘char * const*’ but argument is of type ‘const char **’
hi if i开发者_运维问答\'m passing an unknown command to execvp i\'m getting this error in the errno :
I am trying to create multiple processes using fork() and execvp() calls, but so far I\'ve been unsuccessful. Here is what I am trying to do:
In my program I am taking user input and parsing it into a 2d char array. The array is declared as: char parsedText[10][255] = {{\"\"},{\"\"},{\"\"},{\"\"},{\"\"},
I\'m writing a fake shell, where I create a child process and then call execvp(). In the normal shell, when I enter an unknown command such as \'hello\' it returns \'hello: Command not found.\' Howeve
int main() { ... if(!fork()) { execvp(cmdName,cmdParam); } printf(\"In 开发者_开发知识库main()...\");
