NAME
mkstr - create an error message file by massaging C source files SYNOPSIS
/usr/ucb/mkstr [-] messagefile prefix filename... DESCRIPTION
The mkstr utility creates files of error messages. You can use mkstr to make programs with large numbers of error diagnostics much smaller, and to reduce system overhead in running the program -- as the error messages do not have to be constantly swapped in and out. mkstr processes each of the specified filenames, placing a massaged version of the input file in a file with a name consisting of the spec- ified prefix and the original source file name. A typical example of using mkstr would be: mkstr pistrings processed *.c This command would cause all the error messages from the C source files in the current directory to be placed in the file pistrings and processed copies of the source for these files to be placed in files whose names are prefixed with processed. To process the error messages in the source to the message file, mkstr keys on the string `error("' in the input stream. Each time it occurs, the C string starting at the `"' is placed in the message file followed by a null character and a NEWLINE character; the null char- acter terminates the message so it can be easily used when retrieved, the NEWLINE character makes it possible to sensibly cat the error message file to see its contents. The massaged copy of the input file then contains a lseek pointer into the file which can be used to retrieve the message, that is: char efilname[] = "/usr/lib/pi_strings"; int efil = -1; error(a1, a2, a3, a4) { char buf[256]; if (efil < 0) { efil = open(efilname, 0); if (efil < 0) { oops: perror (efilname); exit(1); } } if (lseek(efil, (long) a1, 0) || read(efil, buf, 256) <= 0) goto oops; printf(buf, a2, a3, a4); } OPTIONS
- Place error messages at the end of the specified message file for recompiling part of a large mkstred program. ATTRIBUTES

NAME
mkstr - Creates an error message file SYNOPSIS
mkstr [-] message_file prefix file... The mkstr command is used to create files of error messages that can be removed from a single C source file, or from multiple source files. OPTIONS
Causes messages to be appended to the specified message file, instead of creating a new file. DESCRIPTION
The use of mkstr can reduce the size of programs that contain many error diagnostics and reduce system overhead in running such programs. The mkstr command processes each of the specified files, placing an altered version of the input file in a file whose name consists of the specified prefix and the original name. To process the error messages in the source to the message file, mkstr keys on the string 'error(' in the input stream. Each time it occurs, the C string starting at the '' is placed in the message file and is followed by a null character and a newline character. The null character terminates the message so it can be easily used when retrieved; the newline character makes it possible to catalog the error message file neatly to see its contents. The altered copy of the input file then contains a lseek() pointer into the file that can be used to retrieve the message to its appropri- ate source file, as shown in the following example of a program that mkstr produces. char efilname[] = "/usr/lib/pi_strings"; int efil = -1; error(int a1, int a2, int a3, int a4) { char buf[256]; if (efil < 0) { efil = open(efilname, 0); if (efil < 0) { oops: perror(efilname); exit(1); } } if ((lseek(efil, (long) a1, 0)) == (long)-1 ) || read(efil, buf, 256) <= 0) goto oops; printf(buf, a2, a3, a4); } EXAMPLES
To put the error messages from the current directory C source files into a file called pi_strings, and to put processed copies of the source for these files into filenames prefixed by xx, enter: mkstr pi_strings xx *.c To append the error messages from an additional source file to pi_strings, enter: mkstr - pi_strings xx newfile.c SEE ALSO
