how to get parameter from file? 1

[allan76]

Hi

I want get parameter from file,Parameters are supposed to be identified with an =, The left part of the "=" is the identifier, and the right part the value.There are several "parameter=" tags in a file.
Please let me know if you know of some way.
thanks.

Well here's one way

#include <stdio.h>
#include <string.h>

int main ( int argc, char * argv[]) {
    char buff[BUFSIZ],param[BUFSIZ],value[BUFSIZ];
    FILE *fp = fopen(&quot;tmp&quot;,&quot;r&quot;);
    while ( fgets(buff,BUFSIZ,fp) ) {
        if ( sscanf( buff, &quot;%[^=]=%[^\n]&quot;, param, value ) == 2 ) {
            printf( &quot;Found p=%s, v=%s\n&quot;, param, value );
        } else {
            printf( &quot;Bad line = %s\n&quot;, buff );
        }
    }
    fclose( fp );
    return 0;
}
