Within the eBPF program, various fields of the context struct can be accessed to retrieve the passed parameters. For example, in the eBPF program, parameters can be accessed by using fields like ctx-&gt;arg1, ctx-&gt;arg2, etc.<\/p>\n<p>It is important to note that the parameters in eBPF programs are not passed according to traditional C function call conventions, but are instead passed through the context structure of the BPF program. Therefore, when writing eBPF programs, it is necessary to determine the form of the parameters and how to access these parameters based on the incoming context structure.<\/p>\n<p>&nbsp;<\/p>\n<p>More tutorials<\/p>\n<p><a class=\"LinkSuggestion__Link-sc-1gewdgc-4 cLBplk\" href=\"https:\/\/www.silicloud.com\/blog\/what-is-the-usage-of-resize-in-c\/\" target=\"_blank\" rel=\"noopener\">What is the usage of resize in C++?<span class=\"sc-gswNZR eASTkv\">(Opens in a new browser tab)<\/span><\/a><\/p>\n<p><a class=\"LinkSuggestion__Link-sc-1gewdgc-4 cLBplk\" href=\"https:\/\/www.silicloud.com\/blog\/how-can-mybatis-return-fields-from-multiple-tables\/\" target=\"_blank\" rel=\"noopener\">How can Mybatis return fields from multiple tables?<span class=\"sc-gswNZR eASTkv\">(Opens in a new browser tab)<\/span><\/a><\/p>\n<p><a class=\"LinkSuggestion__Link-sc-1gewdgc-4 cLBplk\" href=\"https:\/\/www.silicloud.com\/blog\/comprehending-the-structure-and-contexts-of-nginx-configuration-file\/\" target=\"_blank\" rel=\"noopener\">Comprehending the Structure and Contexts of Nginx Configuration File<span class=\"sc-gswNZR eASTkv\">(Opens in a new browser tab)<\/span><\/a><\/p>\n<p><a class=\"LinkSuggestion__Link-sc-1gewdgc-4 cLBplk\" href=\"https:\/\/www.silicloud.com\/blog\/arrow-operator-in-the-c-programming-language\/\" target=\"_blank\" rel=\"noopener\">arrow operator in the C programming language!<span class=\"sc-gswNZR eASTkv\">(Opens in a new browser tab)<\/span><\/a><\/p>\n<p><a class=\"LinkSuggestion__Link-sc-1gewdgc-4 cLBplk\" href=\"https:\/\/www.silicloud.com\/blog\/executing-java-programs-using-the-exec-maven-plugin\/\" target=\"_blank\" rel=\"noopener\">Executing Java programs using the Exec Maven Plugin<span class=\"sc-gswNZR eASTkv\">(Opens in a new browser tab)<\/span><\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In Linux, the parameters of an eBPF program are passed through the context struct of the BPF program.
