A question about printing error message with perror
Dear all,
I use perror in order to print an error message to the standar error. For example
if a C program is called without its two necessary command line parameters
then :
What I don't understand is why there is a second line: ":Success"??
Is there a way to remove it? as I want to print an error message, it doesn't
really make sense to print Success.
Thanks in advance,
Kind Regards,

here the program gives a odd result:
#include <stdio.h>
int main(){
perror("first");
perror("next");
return 0;
}
result:
first: Success
next: Illegal seek
why? any resonable explanation? i found no information about this in man pages.
thanks in advance (2 Replies)
Hia,
this is a very low priority request, but I am slightly annoyed by the behaviour of the tags in the message editor. They behave assymetric in the sense that the opening tag is introducing an empty line, and the closing tag is not, and can't be convinced to do otherwise. I know I am... (1 Reply)

Hello all,
I need to print all the lines before a specific string and print a custom message 2 lines after that.
So far I have managed to print everything up the string, inclusively, but I can't figure out how to print the 2 lines after that and the custom message.
My code thus far is:... (4 Replies)

perror
PERROR(1) MySQL Database System PERROR(1)NAME
perror - explain error codes
SYNOPSIS
perror [options] errorcode ...
DESCRIPTION
For most system errors, MySQL displays, in addition to an internal text message, the system error code in one of the following styles:
message ... (errno: #)
message ... (Errcode: #)
You can find out what the error code means by examining the documentation for your system or by using the perror utility.
perror prints a description for a system error code or for a storage engine (table handler) error code.
Invoke perror like this:
shell> perror [options] errorcode ...
Example:
shell> perror 13 64
OS error code 13: Permission denied
OS error code 64: Machine is not on the network
The meaning of system error messages may be dependent on your operating system. A given error code may mean different things on different
operating systems.
perror supports the following options.
o --help, --info, -I, -?
Display a help message and exit.
o --ndb
Print the error message for an NDB Cluster error code.
This option is deprecated in NDB 7.6.4 and later, where perror prints a warning if it is used, and subject to removal in a future NDB
Cluster release series. Use the ndb_perror utility instead.
o --silent, -s
Silent mode. Print only the error message.
o --verbose, -v
Verbose mode. Print error code and message. This is the default behavior.
o --version, -V
Display version information and exit.
