The contents of the array are safe within the function, however, upon returning to main the data becomes garbled.
section of main:
unsigned short tcp_port = atoi("8080");
const char* workDir = "WhatInthe?";
// Parse command line arguments
if ( parseCmdArg( tcp_port, workDir, argc, argv) == 1)
return 1;
cout << argc << endl;
cout << tcp_port << endl;
cout << workDir << endl << endl << endl;
cout << workDir << endl << endl << endl;section of function code:
int parseCmdArg( unsigned short &tcp_port, const char* &workDir, int argc, char* argv[])
{
char tempPath[256];
bool pathDef = 1;
cout << "pCA tcp_port start: " << tcp_port << endl;
cout << "pCA wordDir start: " << workDir << endl;
cout << "pCA argc start: " << argc << endl;
*/ Command line process takes place here /*
if ( pathDef == 1 )
{
cout << "workDir = NULL" << endl;
getcwd(tempPath, 256);
workDir = tempPath;
}
cout << "pCA tcp_port exit: " << tcp_port << endl;
cout << "pCA wordDir exit: " << workDir << endl;
cout << "pCA tempPath exit: "<< tempPath << endl;
cout << "pCA argc exit: " << argc << endl;The output to console is:
pCA tcp_port start: 8080
pCA wordDir start: WhatInthe?
pCA argc start: 1
workDir = NULL
pCA tcp_port exit: 8080
pCA wordDir exit: /user/ghesquie/cse422/lab3
pCA tempPath exit: /user/ghesquie/cse422/lab3
pCA argc exit: 1
1
8080
/user/ghesqui?
????????
/user/ghesqui? ??
So exiting the function the char array at pCA wordDir exit: is correct, but main show the first 13 characters, but the rest is garbled?
Any suggestions,
Thank you in advance,
