CParser library

File list

Overview

These functions do CCP4-style parsing, as used for processing keywords of CCP4 programs, MTZ header records, etc.

Usage

The following code snippets illustrate how the functions might be used to read from stdin:

int ntok=0;
char line[201],*key;
CCP4PARSERTOKEN * token=NULL;
CCP4PARSERARRAY * parser;
key = parser->keyword;
token = parser->token;
RC = 0;
while (!RC) {
line[0] = '\0';
ntok = ccp4_parser(line,200,parser,1);
if (ntok < 1) {
RC = 111;
} else {
if (ccp4_keymatch("MINDIST",key)) {
if (ntok != 2) {
ccperror ( 1,"MINDIST requires a single numerical argument" );
RC = -100;
} else {
minDist = token[1].value;
}
} else {
printf ( "Unrecognised keyword \"%s\"\n",token[0].fullstring );
RC = -118;
}
}
}
ccp4_parse_end ( parser );
