Prototype: readstringarray(array, filename, comment, split, maxentries, maxbytes)

Return type: int

Description: Populates array with up to maxentries values, parsed from the first maxbytes bytes in file filename.

Reads a two dimensional array from a file. One dimension is separated by the regex split, the other by the lines in the file. The first field of the lines names the first array argument.

The comment field will strip out unwanted patterns from the file being read, leaving unstripped characters to be split into fields. Using the empty string ("") indicates no comments.

Returns the number of keys in the array, i.e., the number of lines matched.

Arguments:

• array : Array identifier to populate, in the range [a-zA-Z0-9_$(){}\[\].:]+
• filename : File name to read, in the range "?(/.*)
• comment : [Unanchored][unanchored] regex matching comments, in the range .*
• split : [Unanchored][unanchored] regex to split lines into fields, in the range .*
• maxentries : Maximum number of entries to read, in the range 0,99999999999
• maxbytes : Maximum bytes to read, in the range 0,99999999999

Example:

cf3 readintarray("array_name","/tmp/array","#[^\n]*",":",10,4000);

Input:

cf3 1: 5:7:21:13 2:19:8:14:14 3:45:1:78:22 4:64:2:98:99

Results in:

cf3 array_name[1][0] 1 array_name[1][1] 5 array_name[1][2] 7 array_name[1][3] 21 array_name[1][4] 13 array_name[2][0] 2 array_name[2][1] 19 array_name[2][2] 8 array_name[2][3] 14 array_name[2][4] 14 array_name[3][0] 3 array_name[3][1] 45 array_name[3][2] 1 array_name[3][3] 78 array_name[3][4] 22 array_name[4][0] 4 array_name[4][1] 64 array_name[4][2] 2 array_name[4][3] 98 array_name[4][4] 99

cf3 readstringarray("array_name","/tmp/array","\s*#[^\n]*",":",10,4000);

Input:

cf3 at:x:25:25:Batch jobs daemon:/var/spool/atjobs:/bin/bash avahi:x:103:105:User for Avahi:/var/run/avahi-daemon:/bin/false # Disallow login beagleindex:x:104:106:User for Beagle indexing:/var/cache/beagle:/bin/bash bin:x:1:1:bin:/bin:/bin/bash # Daemon has the default shell daemon:x:2:2:Daemon:/sbin:

Results in a systematically indexed map of the file:
